Fun game! I loved it when the final boss supersized itself. I noticed that a lot of the pixels were a bit jittery—were you using the built-in camera and camera smoothing with godot or use any kind of scaling on your sprites/level art? One thing you might want to consider is tweaking the collision boxes. In some cases, they felt fair, but in others they felt like they could have been either been more generous or a bit smaller to give the player a bit of breathing room (especially when escaping hits from the enemies). Thanks for making and sharing your game!
