Well done!
I loved the music choice(composition) it really added to the mood of the game. The gameplay worked great, the graphics were nice and clear.
I think my only criticism would be that the game was a little too simple, if you know what I mean. I know it's a Game Jam game, so simple is what we're aiming for, but I think if you developed it into a longer game with a few more stages, or a couple more mechanics, just to keep it from being all luck, that would take this game to a whole new level. Are you gonna keep working on it? Or is it just for the jam?
Anyway, nice submission. I liked it. Good luck with the jam.
