Having bought way more than 300 games for my iPhone so far including Tilt to Live, I think it's an odd game to do an article about – it isn't even new. I've played it a few times but I honestly don't find it all that interesting nor engrossing. I don't even think that it would be in my top 50. Games like Soosiz, Sway, Orbital, Ynth, Geometry Wars, Spikey's Bounce Around, Drop7, Eliss, Fieldrunners, Flight Control, Fruit Ninja, Galcon, geoDefense, geoSpark, Harbour Master, Hook Champ, I Dig It, Jelly Car, Meteor Blitz, The Moron Test, Peggle, Plants Vs. Zombies, PuzzleManiak, Reflexion, Rolando, Saucelifter, Space Miner: Space Ore Bust, StoneLoops, Toy Bot Diaries, Vector Tanks Extreme and a few others would however.
I know different people like different things, but I urge you to play a few of the games mentioned above – start with Soosiz or Sway. They are in my opinion much more innovative, engrossing and worthy of a review.
