I havnt played through all levels yet, i just finished the spira one, and im enjoying it. but theres this wierd illusion that makes it feel like your character/cursor is offset. its because the cursor is 2d while the map is 3D the offset illusion happens when you put the cursor on top of the walls, which in certain angles can make it feel like yourcursor is on top of a wall above your character, but is not. I tested and its not a bug, its just an illusion that might only be affecting me XD
edit, just finished through ultra, what about the other levels? i was looking forward to them D:
