This is visually pleasing! The gameplay feels good and pretty smooth. I could see this becoming an awesome full fledged game. I hope you keep adding to it! I did experience some frame rate drops. Maybe something to do with the particle effect. We work in godot and particle effects always bog up our frame rate. Also my computer is getting a bit old now. So it could just be on my end.
Sweet game and I love the bioluminescent feel!
