Very impressive that you are going for big maps, multiple upgrades, multiple boss fights etc on a two weeks jam. Handdrawn graphics are charming, and there's definitely alot of potential in this game.
I think some prioritization on your workload would be good. Its cool to see quantity, but try to make sure the foundation is as solid as possible before building on top of it. When the game is frustrating to play, it'll deter people from progressing to explore all the content you've made.
Good job! Thanks for making this!
