I love the game, but IMO there are a couple of major bugs to fix before releasing it :
-It often crashes when you switch to another app, then return to it.
-For some reason, the app does not have any sound anymore, after a couple of levels.
-Some time after resuming, the level changes randomly.
Again, I love this game (and you talk about it at droidcon was pretty interesting) but there are a couple of issues to fix.
