The artstyle is fantastic, especially with the ui. This was the first sort of "reverse bullet hell" I tried and it's really fun!
It took me a few tries and readings to understand how the game worked properly, obviously because of the time restraint things like a tutorial are harder to make so that's perfectly reasonable. The gameplay as others have said is really satisfying after you understand how it works and this is really solid as a jam submission. Good choice of sfx and music, and again the visuals just work so well.
The only thing I'd probably say is providing more player feedback through particles, animations, or more sounds would've helped me a lot in understanding how the game worked. I found a lot of the time (since written tutorials aren't exactly the best for me) I was questioning whether I did something good or bad. Again, a lot of these quality of life things are hard to implement during a jam.
I'm probably gonna replay this a bunch when my focus comes back more lol. Really good work on this entry and good luck for the rest of the jam!
