I must say

Very difficult after the first few levels I got to the one after the giant X and than died. Can be very addictive

Two suggests I do have though. The first would be to put some sort of delay after the user dies instead of just booting them straight back to the main menu. As I wasn''t always watching the time, I just kinda went, what the hell happened? Oh, I must have died.

The second suggestion is maybe as the levels get more difficult, give a little bit more time. I found that I hardly had enough time to move a decent number of stones around in the level after the X.

Other than that, really fun game. Ran right outta the box (that''s not terribly common with indie games and was fun to play.

Congrats on finishing a project by the way
