First of all, congratulation on finishing your first game! Thats a big step, and its not an easy one! Your overall gameconcept is quite fun. I am not sure if it is a bug, but sometimes, when I am switching the heart, the other moves in one direction. After a few attempts (me failing hard), there was too little to play more of it. With the addition of a few more features this can be fun,
Overall, nice entry for the jam!
