Found PixelJunk Monsters demo addictive enough to buy. I like it, not too far into it but its a bit hard already.
Also, to anyone who has played Echochrome; I don't think its my controllers but sometimes the puzzle will rotate itself slightly without my input and at random times. This is especially frustrating when the name of the game is to position it juuuust so. I was hoping it's some weird software glitch so I don't have to get another controller (but a good excuse to pick up the rumble one).
