Cool concept. The gameplay and even the character has that Fez vibe. I really liked how you added a tutorial door in the start to try out the 2d / 3d mechanics. But controlling the character is really difficult. Too less friction causing the character to keep sliding and slipping off. Even the cloud platforms were small so it was easy to slip off. If you work on precision of the movement system, it'll be a really cool game, especially with 3d aspect. Keep it up!
