Since NimbleBit's Tiny Tower [Free] launched last week, it has become their most successful game yet. As of this writing, the game has been downloaded 1,230,688 times and is seeing a surprisingly high 2.6% in-app purchase conversion rate which is nearly double that of their previous title, Pocket Frogs [Free]. Over 18 million sessions have been played with an average length of 9.3 minutes. In all, players have played just under 320 years of Tiny Tower.

Even though Tiny Tower has exceeded NimbleBit's expectations, not everything went as planned with its launch. Namely, an irritating crash bug that didn't appear in testing. This has since been fixed in an update that launched today, so if you've had crashing issues in Tiny Tower, download this update ASAP. Another update is also in the works that will apply some tweaks and address some other minor issues affecting a small number of players. Following that, it'll be full steam ahead on content updates to add things like additional floors, bitbook entries, and more.

The best thing about the iTunes family of storefronts is that it carries Sharon Stone's moody and moving flick "Last Dance." The second best thing, which is more relevant to our interests as a site on the Internet that deals with games, is the stunning amount of video game sales.

This week in particular has an awesome sale. Publisher Com2uS is slashing the prices of every single one of its offerings down to 99 cents. Get those wallets outs, dogs. It's time to put those debit and credit cards to good use. Let's take a look at the list:

• Chocolate Tycoon: $1.99 ?�$0.99
• Heavy Gunner 3D: $2.99 ?�$0.99
• Inotia 2: A Wanderer of Luone: $2.99 ?�$0.99
• Inotia 3: Children of Carnia: $4.99 ?�$0.99 [Universal]
• Tower Defense: Lost Earth: $2.99 ?�$0.99
• Third Blade: $2.99 ?�$0.99
• Trapped: Undead Infection: $1.99 ?�$0.99

Of course, a lot of Com2US stock is already being sold for pennies. Check it:

• Slice It!: $0.99
• Sniper vs. Sniper: Online: $0.99
• Caligo Chaser: $0.99
• World of Tunes: $0.99
• Zombie Runaway: $0.99
• Chronicles of Inotia: $0.99
• 9 Innings: Pro Baseball: $0.99

That's a lot of solid games going on the cheap. If you'd like a suggestion, I'd say you should jump ALL OVER Tower Defense. It's an awesome game with tons of levels, hours of play, and fun challenges. The most recent update also patched in some balance tweaks, which means that you can finally finish "Vulcan," AKA the impossible-level-that-I-poured-four-hours-into pre-patch. Of course, you can't go wrong with most of these at this price point, either.

Earlier this month at WWDC, we checked out an assortment of upcoming titles from Crescent Moon Games and their various partners. One of those titles was Topia, an interesting looking sim-style world creation game. It is being developed in conjunction with Glenn Corpes, creator of iOS racer Ground Effect [$1.99] and a former Bullfrog employee who worked on Peter Molyneux's classic strategy simulation Populous.

The Populous influence was apparent in that preview video, as in Topia you're given a colorful planet whose ground elevation can be manipulated and shaped using the touch screen. Exactly what type of game Topia will ultimately end up being is still being fleshed out, but so far we know that there will be various creatures who end up inhabiting your planet in great numbers, and a focal point will be to herd certain creatures together by using ground manipulation.

The world in the build of Topia that we saw at WWDC had tons of interesting characters running around, but they seemed to lack any sort of intelligence. That aspect of the game is starting to shape up as you can see in the following video with commentary from Josh Presseisen of Crescent Moon.

As you can see, Topia can display an impressive number of creatures onscreen at once, and the terrain manipulation and herding mechanics are definitely looking more fleshed out. The game is also quite beautiful, and based on the pedigree behind both Crescent Moon's and Glenn Corpes' previous work I feel pretty confident that whatever Topia turns out to be in the end will be something pretty interesting. You can head into our forums for discussion of the game and we'll keep our eyes on Topia as it continues to evolve during its development.

The last time we gave away a massive amount of promo codes on our Facebook page it was a huge hit, but people had two main complaints: Codes were snatched almost instantly (Argh!! Lurkers!!) and we just did it with no warning. Since I aim to please, I think I've hatched a plan, nay, a scheme to distribute codes in a way that shouldn't necessarily reward those who are the fastest at copying and pasting. Also, I'm giving two hours of notice, which should be more than enough.

The Facebook promo code giveaway will start at 6:00 PM Pacific. That's 7:00 PM Mountain, 8:00 PM Central, and 9:00 PM Eastern. As of this posting, I've got over 200 codes, so it will probably run for a couple hours if it's anything like last time.

What games will we be giving away? Here's a list of some of the games I've got:

• Gears
• Harbor Master
• Max Adventure
• Skipping Stone
• Air Penguin
• Baseball Superstars II Pro
• Zenonia 3
• Illusia
• 9 Innings: Pro Baseball
• Slice It!
• Canabalt
• Pocket God
• Pocket God: Journey to Uranus

I'm sure I'll get some more codes in the next few hours before the giveaway too, so expect some surprise codes as well. If you're a developer and want to be included, send an email with some codes to tips@toucharcade.com. Make sure to include when the codes will expire as I might save some to give away later if we get too many for me to handle.

Head on over to our Facebook page NOW and hit "Like"! In order to not spam people's feeds who have already liked us, I'll be giving away codes in a slightly different way to not flood everyone's Facebook news. Set your clocks, mash your "Like" button, and STRAP IN FOR SOME FREE GAMES!
