This was super unique and well executed. As a really big fan of the idea of higher dimensions and trying to imagine them within our 3D world, I've seen concepts like this before, but only as videos, not as games (with the exception of Miegakure of course). Taking a step down and applying it to a lower dimension feels obvious after seeing your prototype, but its something I wouldn't have thought of on my own. Nicely done and very impressive.
