Super fun! When I hit laser speed 2.0, I laughed so hard that I died :D A couple of pieces of feedback (which I'm giving only because I liked the game so much, and you've said you plan to keep developing):
- If you kill a bunch of enemies all at once, you might level up multiple times simultaneously which leads to weirdness when picking your level up.
- You can kind of trivialize a bit of the combat by circling the enemies' spawn point. They stay grouped together, and you just barrage them all over time. Might be a good addition to have a few spawn points around the map, and the enemies randomly choose one offscreen to spawn at.
- You may want to pause the action when presenting the level up choices, because it can feel hectic with things still going on in the background.
Keep up the good work!
