The movement is . . . really off. Strafing left and right pushes you in some weird direction. One play, strafing kept pushing me towards the start of the maze, the next it was pushing me behind the camera, either way I found myself accidentally hugging the walls most of the time. Just that alone made it difficult to predict where I would move, not in the "this makes gameplay hard" sense, but in the "the camera moved in a direction I did not expect" sense that gave me motion sickness. I do not normally get motion sickness.
I . . . don't know if I beat the game? It was not clear what happened there. I got through three gates and touched a purple and pink striped thing.
