This is really cool, it´s gorgeous, great use of graphics, and it´s a very polished game for a 8 hours work. Maybe it needs some more balance, but it increases a lot the fun over game time.
The bad part is that this game was made for A HUGE AMOUNT of game jams. I can accept if 2 or 3 game jams have similar approaches and you make a game for this specific jams, but… more than 20 game jams (1-bit game jam?? Nope, you are doing it wrongly ^^!).
