OMG how did you manage to make such a polished, well-designed, and solid game in such a short amount of time as a solo developer? That's really impressive.
I really liked the Prisma mechanic, it was fun to play and felt very well thought out. I could see the progression, difficulty curve, and level design throughout the game, and it feels like it has a ton of potential. Great work, and I hope to see more of it in the future! :D
