Cool game! The simple shapes combined with the shaders is a nice look. The XP collection with right-click is a nice addition. Audio is good as well. Here's some notes for you:
- Would be nice if you enabled the fullscreen button, or at least increased the embed size (these are both settings on itch, no need to change anything about your game)
- The first time I hit an enemy, the game freezes for a bit because it's compiling the particle system. You can avoid this by emitting all particles at the start of the scene (you can do it behind a solid ColorRect so that it's not actually visible).
- The upgrade selection screen feels a bit unresponsive. Maybe make the cards get bigger when hovered, and leave the selected card on screen for a brief duration after removing the other two.
- The game was too easy. I barely needed to use the dash at all.
