Really great little game! Liked the ability to dash being tied to having energy currently on you.
Had a slight issue with the particle effects, each time a new one had to be played for the first time the entire game froze for a few seconds - it's something of a known issue for Godot with HTML exports. I'd recommend trying out the solution here (https://github.com/godotengine/godot/issues/87843) and displaying your particles off screen at the very beginning for 1 frame, allowing them to essentially load before the game properly starts!
