Earlier this month, Donut Games released their newest iOS title into the App Store called Chicken & Egg [99�]. This simple puzzle game featured a theme that was perfect for the upcoming Easter holiday as well as the core components that have become synonymous with many of Donut Games' previous releases: colorful pixel art, simple mechanics, plenty of levels, and a 3 star grading system.

However, what was most interesting of all about Chicken & Egg were the things that had never graced a Donut Games release before: it was a universal app, had high resolution graphics for iPad and Retina Displays, and used Game Center for online leaderboards and achievements.

This was great news for a number of reasons. As an iPad and iPhone owner, I always appreciate when games are universal as I can use them on either device with just a single purchase. Also, pretty much all of Donut Games' titles have online leaderboards, but they required being pulled out of the game and into the Safari browser in order to view them which was infinitely annoying. Now with Game Center, that isn't a problem.

So, that's great for Chicken & Egg and all, but what about the rest of the Donut Games library? Well, they have informed us that every new game going forward will include these new features, but what's even more impressive is that they'll be going back and adding them into all of their previous games as well. The first game to be getting the retroactive universal/HD/Game Center treatment is one of the first traffic management games Traffic Rush [99�].

In fact, while Donut Games is in Traffic Rush tinkering around, they're taking the opportunity to improve upon the game by adding an entirely new mode called Rail Rush. As you can see from the video below, Rail Rush takes the idea of controlling the speed of various lines of traffic and applies it to trains on a track.

We make no effort to hide the fact that we love Donut Games. Their titles are consistently enjoyable and a great fit for mobile gaming, and with nearly 30 different games under their belt there's bound to be a little something for everyone. I'm not sure that every single one of their older games will be receiving as robust a package as the new Rail Rush game in Traffic Rush, but I'm definitely excited to have them get universal iPad support and Game Center integration. Anything beyond that is just gravy.

Be on the lookout for the first batch of updates to Donut Games' back catalog, including the Rail Rush update, to hit in the coming weeks.

One of the more interesting bits of development drama to come out of last year was when Mobile1Up went rogue and decided to port Lemmings to iOS. Sure, it was undoubtedly doomed from the start but it was still incredibly entertaining watching them liveblog the whole process as they ported over their entirely remade Palm OS version of the game. The liveblog mentioned is still online, and still worth reading (start from the bottom) if you're even vaguely interested in what's involved in porting an old game to iOS.

It wasn't much of a surprise that the Lemmings project was served with a cease and desist order from Sony, who is sitting on a number of forgotten retro IP's similar to Lemmings. Regardless, there are two universal constants in the world of gaming: Haters are gonna hate and lawyers are gonna… lawyer? So with the unofficial Lemmings port officially shut down, the developers decided to turn their existing completely rebuilt version of Lemmings into something that's just barely different enough to legally be in the clear.

Enter Caveman [$1.99] and its associated Caveman HD [$3.99]. It's Lemmings right down to its core, except without the actual Lemmings themselves. Given the circumstances, I would have opted for something a little more funny than cavemen, like lawyers, but I suppose it's in Mobile1Up's best interest to not push the issue much further.

It's great to see the whole Lemmings port project reaching a conclusion. If you've been looking for an authentic Lemmings experience but don't mind a bit of a reskin, make sure to give Cavemen a try.

At the beginning of February, Ravenous Games released League of Evil [99�/Lite], a fast-paced platforming game with a retro look and feel. We liked League of Evil quite a bit in our review, noting its well-designed levels, fantastic pixel art, and solid controls. League of Evil originally came with 54 levels to play through, with several goals to attain on each that offered a nice amount of replay value. Just a couple of weeks following release, the game was updated with 30 additional levels themed after fellow developer Halfbot's The Blocks Cometh [$1.99], as well as 18 "impossible" levels that came with a brutal degree of difficulty.

Over the weekend, League of Evil received its second substantial content update that brings another new episode filled with 30 brand new jungle-themed levels. This update also brings online leaderboard that join the already implemented OpenFeint achievements. There's a leaderboard for each of the 4 episodes � Weapons of Mass Destruction, The Blocks Cometh, The Impossible Missions, and Welcome to the Jungle � and once you've completed every level in an episode your total completion time for that episode will be uploaded online.

The App Store is a veritable smorgasbord of great platformers, and since release League of Evil has hovered near the very top of the list for me. With all of the new levels from these last 2 updates that have more than doubled the size of the original release, it just keeps getting better. Plus, Ravenous Games has said in our forums that they are currently working on a level editor for League of Evil that will come with the ability to share created levels. There's no set release for this feature, but the prospect of creating my own levels has me really excited.

If you haven't yet picked up League of Evil, now would be a great time to do so as it's supposed to jump up in price with this latest update to $2.99, but as of this writing can still be bought for just 99�. The price can change at any moment though, so best to act quickly if you're interested in buying the game, and don't forget there's a free lite version to try as well.

When an off-shore oil rig accidentally drills right into the head of a giant red sea creature named Destructopus, the monster awakens to find that its beloved planet Earth is being ravaged with pollution by the human race. To right this wrong, Destructopus does the 2 things he knows best: destroys the many man-made structures that are polluting the environment, and kills the humans that are exploiting nature's cute and cuddly creatures. Such is the story of the aptly titled Destructopus!, an upcoming game from developer Glitchsoft.

Destructopus! is a side-scrolling arcade game where you'll control the lumbering red behemoth as he lays waste to anything and everything in his path. Destructopus can use his mighty jaws, claw-like tentacle, or eye laser to destroy the many structures in the game as well as fling around the vehicles and humans on the ground and in the air. It feels like a throwback to the classic arcade game Rampage, with a ton of little details in the environments and many elements to interact with.

Destroying things is not only fun, but will earn Destructopus green orbs which can be used in an in-game shop to purchase upgrades and will also determine how many stars out of 3 you will score for a level. While many of the upgrades can be bought with these green orbs, some of the more interesting sounding ones are only available by in-app purchases, which is kind of a bummer.

We've had a preview build of Destructopus! for the past couple of weeks, and have been enjoying it quite a bit so far. The mechanics are pretty simple and at times it can feel a bit button mashy, but causing a huge amount of destruction is very satisfying. Plus, in later levels the enemies increase in quantity and difficulty, requiring quite a bit more strategy and upgrading in order to succeed. Destructopus! has already been approved by Apple and is slated to release on May 3rd. Until then you can check out the discussion of the game in our forums and we'll take a closer look at this title when it hits the App Store.

Last month, indie developer Ryan Mitchell and his studio Banshee Soft released Mission Europa into the App Store. Combining a deep RPG experience with a first-person shooter, Mission Europa is really unlike anything currently available for a mobile platform like the iPhone. Now you can get a taste of this with the recently released lite version of Mission Europa.

The complete game is spread across 5 episodes and 170 missions, with 50 different levels to explore and at least 50 hours of gameplay. There are a ton of different armor types, equipment, combat skills, and weapons to customize your character with, not to mention an item and equipment creation system that expands that even further. Beyond the impressive single player offering is an online battle arena where you can take your created character into battle against players from all over the world, adding what amounts to endless replay value to the title.

Strictly speaking in terms of content and depth, Mission Europa is unmatched, and the fact that the entire game was built from scratch by one person over the course of 2 years is an insane accomplishment to say the least.

Unfortunately, the complexity and scope of the game also means that Mission Europa will only appeal to a certain kind of player. This would be a complicated game on PC or consoles, and the fact that it's on a mobile platform and squeezed onto a tiny screen only compounds this issue. The screen is incredibly cramped with control and HUD elements, and the menus and general user interface feel clunky to use. We wanted to enjoy Mission Europa when it came out, and invested many hours trying, but found we could just never get into the game.

That's not to say everybody will have those feelings though, as Mission Europa certainly does have an audience. It has one of the most popular threads in our forums which is always abuzz with discussion of the game, as well as a very active item trading thread where players can swap different items and equipment from the game. Ryan has also been extremely active in our forums and on his own website taking suggestions and feedback about the game in order to shape the best experience possible.

Because opinions on Mission Europa have been polarized and it is a very niche title, it's great to see that a lite version has been released so you can decide for yourself if it's your particular cup of tea. Mission Europa Free Edition [Free] contains the first 2 levels of the game and over 2 hours of gameplay, which is more than enough time to see if you would enjoy the full game or not.

If you do like what you see, the full edition comes in 2 flavors � Mission Europa Standard Edition [$3.99] which is the base game with additional episodes available as IAP, and Mission Europa Collector's Edition [$9.99] which includes all episodes and access to every level right of the bat as well as the ability to wear enemy armor. Either way, I'd definitely suggest at least downloading and trying out the lite version of Mission Europa, as it's an impressive offering as a mobile title and provides more content than practically any other game in the App Store.
