Very trippy game, but very cool! Love how the skill tree is the map AND is at your center, thats handled brilliantly.
At my first few attempts i felt like the rings werent doing anything, it took me a few tries to finally understand how their feedback worked. Maybe you could add a sound cue if something works? Or maybe you could make it a bit more interactive, where smaller circles spawn inside the powerup rings that you gotta stand on for a few seconds. The game is also a tiny bit loud, but thats all I can really say.
Great game! I can see you working on this for longer, and with a little bit of polish it will turn out brilliantly
also i beat your score EHHHEHEHEHEHEHEHEHEHEE
