It's not that the game is bad, it's that there is no game at all. You have a functionning mechanic (and it works, good job on that), but unfortunately that's not enough. It lacks every other aspect of a game. Maybe you wanted to enter your first jam and pull out something no matter what. But I'm afraid you rushed a few key steps. I'm sure you can do way better next time. Don't lose faith and work harder ! ;)
