Pretty sweet concept. I like how you get sound when rolling over the tiles. That adds nicely to the gamefeel. The sound is really sharp however and soon started hurting my ears. Check out sfx-er.
The controls are nice. It would be even better if they felt good. RIght now the movement feels rather off. After 2 levels this and the menu that kept interfering after the lvl frustrated me so much that I quit.

A very addictive game. however the some of the panels seem to disable the jump. i'm pretty sure its a bug. u may want to check it out.
