Theorem has a lot of things going for it, a simple premise; you can’t land the cube on a side that has an X. Rotate the cube from the start point to end point around various obstacles. It’s explained and executed beautifully with distinct shapes and colors to help identify everything’s purpose. However things begin to fall apart near the end, as the teleporters were quite buggy and sometimes would glitch your cube to a side that it shouldn’t be on and softlock you. However that is the largest issue facing a rather solid game overall.
