Always love to see 3D submissions! Will say, I did run into significant stuttering when running the game. Wished for a download link tbh over a web build but it wasn't enough to stop me from playing. Art looks great! Polished and stylized!
When it came to gameplay, I noticed at a certain point that you didn't really need to kill any of the enemies. Spamming jump basically made you invincible and I zoomed to Level 25 until stopping. If y'all do continue it, it would be cool to maybe introduce more enemy types, and possibly even make it so the player has to clear rooms (kind of like Binding of Isaac).
Regardless, cool stuff!
