Really funny game, the most original metroidvania I've seen, including the items. Jumping was kinda floaty, but there wasn't much platforming so it's not a big problem. Combat was a bit off since just pushing the attack button wasn't enough, took me some time to realize that but I was able to beat the bouncer after I did, quite a challenging boss but not too difficult.
Loved the music, especially the first song.
Continuing the game didn't seem to work after coming back later.
One nitpick also, the health bar is quite small and hard to see.
