The concept is fun, trying to balance the baby. The music was really intense; maybe a bit too intense, as it doesn't feel like it fits with the art style of the game, and that may be intentional.
I did like that as the game progressed the balance bar was getting a little smaller, adding difficulty to the game.
I think I would just need a piece in the game that says "press and hold the space bar to hold the baby" or something along those lines. It took a little bit to figure out the controls, but once I figured it out, it was fun.
