Nice game! Gave me some Binding of Isaac vibes to it. For something made in just a few days this is pretty big. There are a few bugs I noticed but the only seemingly game breaking one was when i first booted up for some reason the player wasn't visible, so I had to reset.
Some bugs I noticed just for reference:
-In some rooms it looked like I spawned at the bottom instead of a side door I walked through.
-Some dagger turrets seem to die on their own?
For features having a personal HP indicator (hearts, number, indication on player) would have been appreciated, and so would some indicator for the bad powerups.
All in all a cool game and was satisfying to kill the heart and watch it crumple! With a bit more polish this would be awesome! Great work!
