Super fun game! I loved the art-style and music most tbh, both of them really reminded me of deadcells (and the prisoner thing too lol). Here's some feedback for ya:
1. The jump height felt a little too high, like if I'm trying to jump to platforms I can't even see I would consider that a little too high honestly.
2. Another thing about the jump, is that pressing the space bar really quickly to dodge an incoming enemy felt really difficult cuz the default height was so low, so try to have a default height that the player will go to that is higher than enemies, and if the player wants to jump higher, allow them to keep holding the space bar to get a little bit more jump (this is pretty minor but I felt like it was important to mention).
3. Lastly, there might be a bug with enemy spawns where after a few attempts enemies just stop spawning completely when you press a new run. After I restarted the whole game I was able to continue though (and I beat it, awesome ending btw lmao).
Overall really good man, congrats on your first GWJ!
