Bullet collisions didn't work for me-- I couldn't hit enemies, and they missed me 95% of the time. I wasn't really sure what was happening with the cards being picked up either. It seems like the bones here could be good, but interacting with elements needs to be fixed to say for sure.
The art looks pretty decent, it gives me Zelda dungeon vibes in a good way. I'm actually not a fan of the music, it's a bit dissonant in my ears unfortunately.
