This is really great as a first game project, I'm impressed! This might be the juiciest submission I've played so far this jam, really loved the sounds for all the actions. When I got to the spike field I thought I was stuck but decided to try and see if there was a Hollow Knight style pogo and was happy to be right! Really like the spin jump animation too, Samus would be proud.
I think my only real criticism is it feels to hard. One hit deaths are really punishing, but maybe that's what you're really going for.
Awesome job, can't wait to see more from you!
