i didnt encounter any bugs, but i thought i did when i found out i could refight the vase slimes to get more levels.
On my first playthrough i didn't even notice there was a second room. I like the concept and the small grind, i like getting stronger in rpg's. Someone in the comments mentioned three bosses, but the game is over once you beat the head hat-slime, right?
Balancing was a little off though, you can just spam attacks and win the game without ever needing to heal.
Still, i had a lot of fun, thank you!
