It is just a simple tilt-based game, but as far as the game's core concept is concerned, it's really cool– Especially if you've got an extensive Facebook photo collection.

The controls can be a point of frustration.

It's a great experience, but I think you need to be in the proper state of mind to enjoy it, and even then I'd lean more towards describing the game as "this is really neat" rather than "this is really fun."

There is a lot to like in Grimm, and if you can deal with tilt-only controls and some minor frustrations, it's worth taking a look at.

The game is basically a trippy combination of Asteroids and Space War! played on the screen of the iPhone or iPad and marks the first in a series of Llamasoft games that are part of the "Minotaur Project," an effort by the developer to release numerous titles featuring retro gameplay, progressing forward from the Atari VCS aesthetic to the VIC 20, Commodore 64, and beyond.

It may not blow you away with high end visuals, and the core gameplay is pretty simple and won't appeal to everybody, but GeoSpin is a catchy and original game that is executed very well.

Besides the lack of Retina Display support, Bouncer Boot Out could really benefit from some sort of online high score tracking, such as Game Center. But even with these two shortcomings, it's still a really solid game.

Although it won't be everybody's cup of tea, SpikeDislike is a simple and fun challenge that's worth checking out.

The simplest way I can put it is that Mad Skills Motocross is pure fun.

Cave Bowling is a fun physics game that comes packed with everything we've come to expect of Donut Games. My only real nitpick is I wish it came loaded with Game Center, as Donut Games' web-based scoring system leaves much to be desired.

A smart, simple, and endearing platformer. The core mechanic might sound a little abstract, but don't let that get in your way.

This isn't the scariest game on the planet, nor is it the best put together. The combat in particular is a black eye. But there's a lot in Dead Space to keep you engaged and there's some points of great design that I think you'll appreciate - especially if you're daring enough to play this on your sofa with the lights off and some great headphones on.

I know it's not the same sort of game, but if you like Angry Birds and its ilk, I think Cover Orange will be worth your while - there's just a spiritual similarity of sorts going on there.

There is just so much going on in Bug Heroes, it's amazing that it all blends so incredibly well.

Honestly, any negatives I can think of about Pocket HalfPipe are quickly forgotten once you get your thumbs on the board. It's just so much fun. Some additional variety in the form of tricks, clothing, or environments couldn't hurt, but what's here already is still really solid.

It boasts a tutorial that is incredibly approachable, making the game appropriate for even the most casual of puzzle gamers, while offering a top-end that's full of strategy, a bit of luck, and an entire trail of character development decisions.

It's disappointing that finding and collecting items is really all there is to do in 1000: Find 'Em All! though, as the game world is rich and detailed and screaming for further interaction.

A great game to pick up if you are bored of other match three games but don't want to give up on the genre.

Unfortunately, the cool premise is about all there is to it.

Dungeon Defenders iOS is a deep, sometimes entertaining game… but the controls are a core, critical, nasty flaw that I don't think can be "fixed" or addressed in any meaningful way.

MotoGP 2010 isn't the worst racing game that I've played on iPhone, but it's far from the best.

It's a winning formula that is as simple as it is effective.

Phoenix Spirit is a cool game of exploration, filled with well drawn pixel art, immersive music, and a neat game concept that any fan of Metroidvania side-scrollers shouldn't miss.

Split/Second isn't a must have but may appeal to those looking for a different and far more arcade-y racing experience.

Omium is as much fun as you make it, as the idea behind the game is that players take turns playing as each side to see how long they can survive.

Pretty darn fun, and with 32 levels, OpenFeint integration, and a phenomenal musical score, it should keep you entertained for some time.

My other biggest point of contention is having to play for an extensive period of time (or spend real life money) before being able to unlock the landscape mode. It just feels like a cheap aspect to an otherwise excellently presented game.

If you have a soft spot for Namco's famous mascot, or have nostalgic feelings for the original game, then give Pac-Attack a look.
