Interesting but The controls are pretty difficult. Check "threedimensional maze" app for a much friendlier system. Although this app has a long detailed tutorial which tells about multi camera view it's still almost impossible to navigate inside the maze after you understood it. I guess this complex system only really pays out in 5d+. The whole app must be free for gods sake. Math geeks hate iap, just make a paid ads-free version or something.
Every time I win, I have to increase the size by one; but I beat your game: It won't let me play the 4×4×4×3×3×3×3. But I'm trying not to complain too much, because of the way you help us visualize the higher dimensions; and the quality you put into your work is amazing! And the performance issues would probably depend on the hardware.
