Really fun game. I loved the trippy visuals and enjoyed the layered music! I'm surprised you pulled off the idea with no major bugs in such a small time.
My biggest issue was that sometimes it's difficult to see what you can and can't go through, I didn't realize there are some walls you can go inside until after some trial and error. I also pressed space as soon as the game started and fell down instantly, skipping the tutorial initially and not knowing you can dash. The game is close to perfect still!
