This is such a cute little game. I loved being able to cast spells and then upgrade them. I wish the upgrades were still actual words because it was hard to see each letter past the colors changing and the camera moving when you were near the crystals. I also think some more direction for the players would be helpful but I had a lot of fun regardless. Oh an also, maybe developing the story more so that the invincible theme at the end makes more sense but that's coming from someone who couldn't solve the last puzzle, lol, so maybe I'm missing something. Awesome job! I hope you develop it further, truly.
