Enigma

An accelerometer controlled.. Uhh.. Puzzle game...

Overall- 3/5
Enigma is an accelerometer controlled game. In it you accelerometer-y control a ball, rolling around on what seems to be a pool table. A pool table full of deathtraps. Your goal is to avoid aforementioned deathtraps, while bumping into question mark blocks, which then receive a color, and must be paired with a different block of the same color. Kind of like those matching cards memory games, only with traps. And death.
Lots of death.
The accelerometer works great, the game plays very well, but the ball runs really fast (I had a hard time until I dropped the mouse sensitivity to 1 and even then the max speed is frustratingly high) and the interface is very touch friendly.
The game itself has loads of levels (the tutorial alone has 66 levels) so you could probably play this game for days.
The game is very user oriented- Your scores can be uploaded, statistics are then made, and an info page exists for every level with average scores, and other bits of info, levels can be built and uploaded, etc.
Music and sound exist, but were muted after five minutes of playing.
As for gameplay, one thing that really bugged me is the lack of a real tutorial, I've played the tutorial, but it doesn't feel like one- there's no guidance, no explanations before the levels start, and the game does get increasingly complex.
All in all enigma's a good game, gets surprisingly complex and interesting after a couple of levels, and can be very challenging, not to mention the fact that your score is compared to scores of other people, which always helps me enjoy a game.
My only beef with the game is that in spite of everything it still managed to get repetitive at times, and the controls, while very responsive, were still a bit hard to play with, as the ball's max speed is very high. At any rate, those issues aren't that big, and shouldn't prevent you from at least trying the game out.
