Nice game. But I couldn't understand the game mechanics from the game it self, until I read the comments. The art was good.
I had the same problem as AshesElite (half of the game screen is hidden in the top), and that's happen with other games in the jam, but they leave an option for full-screen or resizing the screen game, I had to higher my display resolution for it to show the full game.
Overall the game was enjoyable. Nice job guys!
