Very cool game, even though it might not be the most innovative one. I really like the execution and the pixel art. The gameplay feels really great and on point. Maybe the difficulty in the first few levels could be a bit lower. Especially in a game jam entry, where most people only play for about 5 - 10 min, I think it is super important to make the first few levels super easy, so that people have an early success. I know as the developer these levels might feel super easy for you, because you tested them so many times and you are pretty good at the game by now. However, for us newbies who play it the first time the first 3 levels are already pretty hard.
Congratulations to this very good and very polished entry! Well done.
