The mechanic is promising, but I was a bit confused on which tile does what, and the help screen could have worded this in a better way. Also, this game would really benefit from an undo feature - there were cases where I either thought my move was bad or that I moved a tile and then I accidentally moved it again, while I was trying to select a different tile (which I think is also another problem). Restarting the whole level to correct one move is, in my opinion, a very bad thing for a puzzle game.
The visuals and the audio was great though. Good luck!
