Incredible game! Really nice mechanics of killing enemies for mana and using it to respawn or view unreal objects. Wish there’d be some tutorial, though - I only noticed you can gain mana and use it for respawn on level 2, and that you can press [Q] on level 4 (reached there by simply memoizing which platforms are real). Unreal walls are a bit off-putting as well, since you often go through them and fall down immediately, so you have to turn your camera in such a way the it gets inside the walls and can effectively see through thanks to back-face culling.

Anyways, enjoyed the game a lot, great job!
