Great job on your first published game, especially since it was for a short game jam. Here are some suggestions for your game: the staircases are very hard to climb, coyote time could potentially help with this (youtube.com/watch?v=ePoNO5P1Csc). The pickups are a little hard to notice, although that isn't a super hard fix. The combat is good but it does feel pretty slow. Anyways, good luck with game development!
