This is the most minimalistic take on a theme I have seen, but this is a good thing since jams are about making a game in a short time and you have to be prepared on every problem (so don’t be like me which encounters problems everytime :D ). The game is quite fun and getting that heart for extra chances is a extra layer of reward that really helps making it a good game, since balancing the game especially with randomness is important and you made an interesting entry. Congratulations!
