I travel a ton, both for many of the conventions and events we cover on TouchArcade, as well as because staying in one place for too long is boring. Traveling a lot is liberating for many reasons, but mainly because you realize just how little of the stuff you own you actually need. Specifically, from a computing standpoint, I've got my entire infrastructure down to a single laptop bag which houses absolutely everything I need for TouchArcade and all other things I use my computer for.

When bag space is at a premium, you rarely have room for any "unitasker" as Alton Brown puts it, which sadly leaves many traditional gaming accessories without a place in my mobile arsenal. I've made a special exception for the Fling iPad joysticks, but I haven't had an actual USB gamepad for ages. Normally this isn't much of an issue, but since 2011 is the 25th anniversary of both the Metroid and Zelda series, I've taken it upon myself to replay both series in emulators as carting my originals (and associated consoles) around just isn't realistic.

This is where Joypad [$2.99 / Lite] comes in. Utilizing a small iOS app combined with a companion program running on your Mac or Windows PC, you can use your iPhone as a game controller. Setup is simple, and basically just amounts to having both your computer and iPhone on the same wireless network while having both the iOS app and the companion program running. In the Joypad Connect computer program you'll then select one of the pre-sets for mapping buttons to keys, then select your iOS device from the list of devices and you'll be good to go. If you're playing an emulator or game that uses different keys, you can create a new profile for that, and go to town mapping the controls it uses to the virtual buttons of Joypad. It all works really well.

This will be somewhat obvious if you've played the various emulated games that Sega has released on the App Store, and other classic titles released by other developers… but often times these classic games simply require the precision and tactile feedback of a real controller. So, how well Joypad works is largely dependent on two factors: 1. How good you are at handling virtual controls. 2. The control demands of the game you're emulating and whether or not those will even jive with Joypad. Specifically, games that require super-precise D-pad dancing aren't so great. Also, games that require you to hold down more than two buttons can be hit or miss depending on what buttons they actually use and how often you need to use that button combination.

Another issue I've randomly run in to is that Joypad is highly dependent on a low-latency WiFi network. It has worked great in most locations, but this week I've been staying in an area of Barcelona with so many WiFi networks that my menu to select them on my Mac scrolls for ages. With the local WiFi signal spectrum this jam packed, I've had issues just browsing the Internet, so it's not much of a surprise that Joypad also suffers. I don't expect this to impact most people, but if you live in a super-crowded urban environment just be aware that your game controls will only perform as well as your local WiFi climate will allow.

That being said, Joypad is without a doubt one of my favorite non-game apps that I've tried lately. Sure, it was released almost a year ago now, so it's very existence will likely be old news for some. However, if you're like me and never really had reason to look for something like Joypad before, now you know about it. $3 for the app is also considerably cheaper than any worthwhile USB gamepad, and while it is by no means a substitution for real physical controls, it sure is a great travel companion.

If you were hanging around the arcades back in 1983 (and I'm willing to bet at least some of you were), then you probably remember the classic game called Tapper. In Tapper it was your job to man several counters in a bar and rapidly serve drinks to approaching patrons, while simultaneously collecting their empty glasses before they slide off the end of the counter and shatter all over the floor. Tapper was an extremely fast-paced game and notoriously difficult, and it is also well known for originally being sponsored by Budweiser and featuring their logo throughout the game.

This aspect of Tapper didn't go over too well though, as it's common knowledge that kids love video games (as do adults!) and placing a game laden with Budweiser branding in arcades that are crawling with children is generally frowned upon. The next year, Tapper was rechristened as Root Beer Tapper and featured nearly identical gameplay minus the Budweiser logos and with root beer as the beverage being served. Root Beer Tapper is the game that is more commonly recognized out of the two as it went on to receive various home console ports and has been included in numerous retro compilations.

Recently, it was announced that Warner Bros. and developer Square One would be releasing a brand new version of the Tapper franchise for iOS called Tapper World Tour. Tapper World Tour will retain the same basic gameplay elements of the original Tapper and Root Beer Tapper but will have you working in bars around the world, and instead of just serving your average beer to patrons you'll be serving drinks that are appropriate to the locale that you're working.

Here's a side-by-side comparison of the original Root Beer Tapper 1984 arcade game and Tapper World Tour on an iPhone 4 (click images to enlarge)

Perhaps the most exciting development from Tapper World Tour is that the game is being drawn and animated by the legendary Don Bluth, who has worked on countless classic animated films for studios such as Disney and Fox but is immediately recognized by gamers as the artist behind classic laserdisc arcade games Dragon's Lair and Space Ace. You can check out Tapper World Tour in action in the first trailer for the game:

The developers aren't getting any more specific about a release date beyond "within the coming months" but we do know they will have a playable build of Tapper World Tour at GDC which starts at the end of this month. We're eager to get our hands on the game to see how the new version plays out on iOS. Personally, a touch screen seems like a perfect place to slide beers down a counter towards thirsty drinkers, but I have no idea if that is actually the mechanic used in the game. Make sure to check out the official Facebook page for Tapper World Tour and we'll bring you more information on the game�just as soon as we get it.

After being released in October of 2008, JellyCar [Free] went on to become one of the most popular titles in a young App Store. JellyCar is a 2D side-scrolling driving/platforming/puzzle game that utilizes a soft physics engine, meaning practically everything in the game has an extremely bouncy, Jello-like behavior. The goal was to complete each course in as little time as possible by accelerating forwards or backwards, tilting the angle of your car using the accelerometer, and occasionally enlarging your car to a massive size to get past some of the terrain. JellyCar launched for free with a healthy amount of levels to play, and since release has been downloaded nearly 6 million times.

A little more than a year after JellyCar hit the App Store, a sequel was released aptly titled JellyCar 2 [99�/HD]. JellyCar 2 maintained the core gameplay of the original, and besides adding new levels there were also a number of new features included as well. There was a simple editor where you could create your own levels, a long jump mode where the only goal was to launch your car as far as possible, and an odd puzzle game called Jelly Factory where you sorted various Tetris-like pieces. There was also the ability to customize your car's colors and utilize two special powerups to make your way through the game.

While it was neat to see so many interesting features in JellyCar 2, it felt a bit scatterbrained as it moved away from what made the first game so much fun � mashing through cleverly designed levels as fast as possible. Last week, series creator Walaber and Disney released the third entry in the series, JellyCar 3 [99�], which ditches a few of the features from the last game and refocuses on what made the original JellyCar so great. Despite a couple of hiccups, JellyCar 3 manages to be the most fun JellyCar yet.

JellyCar 3 comes with 50 brand new levels to play through, each one with a hidden exit to find and 3 stars to earn based on completion time. The levels are much more interactive than they were in the previous games, with a ton of moving parts and platforms that will launch your bouncy car around. The powerups from JellyCar 2 return, one that causes your wheels to stick to any surface and one that ties a balloon to your car and lets you float around a level. Both of these special items are used to great effect in the puzzle-like designs of the levels.

An interesting new feature in JellyCar 3 is the ghost replay which allows you to race against your own ghost run through a level as well as those of anyone online. JellyCar 3 uses Game Center for achievements but has its own online leaderboard system for tracking high scores and replays. Unfortunately, creating a username to upload my own high scores seems to be broken for me, as well as some of the players in our forums, though the developer is looking into the cause of this problem and will issue a fix as soon as possible. I am still able to download and race ghosts from the global leaderboards from people who haven't had this issue, and I'm able to view and save locally the replay from any completed level in my own game.

One slightly odd new feature in JellyCar 3 is the ability to rewind a short portion of your run if you happen to screw up. The game initially comes with 10 rewinds to use, and you can buy packs of rewinds as IAP if you need more. I've heard mixed feelings about this addition. On one hand, the rewind feature is completely optional and it lets the more casual players progress in the game without having to completely redo a level if they mess up. On the other hand, the entire game is built around the idea of completing a level in one run as quickly as possible. Giving people the ability to fix their mistakes until they achieve perfect runs ruins the integrity of that aspect of the game. Regardless of how you feel about this feature it's important to know that it's there, and personally I'll never use the rewind as that would ruin most of the fun for me.

Overall, JellyCar 3 is a fantastic effort. The 50 levels are a ton of fun to play through and figure out, and Walaber has promised even more levels with future updates. The graphics are also much improved over the previous games with far more animated bits throughout the levels and support for the Retina Display. The car customization is back too, and beyond just picking the colors for your car's body and wheels you can actually choose from a bunch of different designs or even draw your own from a simple in-game design editor. I've surprisingly spent a ton of time just creating cool cars by drawing stuff in the templates, which has proven to be really fun.

If you have no idea what JellyCar is, then you should definitely download the free original to see what it's all about as the subsequent games are very similar. If having a level editor and mini games is really important to you, you'll have to stick with JellyCar 2 for those features. If you're any sort of JellyCar fan at all though, JellyCar 3 is easily the best one yet and is highly recommended.
