Sprite design is excellent. Coyote timer (jump grace period when leaving ground) is appreciated. Volume controls were put to good use. Mechanics are well integrated and introduced. Respawn mechanic is quick and easy and solid enough to be used to reset position when you need to - small exception for entering rooms from the opposite side.
Encountered an issue when walking back out of the entrance of the multiple trap bullet launchers room with the wood. Character appears stuck in the environemt and not visible. Found all potions, did not complete game because of this.
Potion particle effects are plentiful, though I find they sometimes cover up the thing you’re trying to throw them at (IE enemies). I also only found out you could throw upwards by accident. Throwing potions also locks you out of jumping. Firebombs are a touch hard to work with and I thought they were an environmental hazard when I first encountered them and turned back to try find some sort of powerup to get past it.
