I haven't actually finished the game yet, but the fact that you made a 4D level for a game jam makes this an automatic 5 stars for me
The game is also very well polished around its jank. In the first level with the superliminal blocks, I managed to drop one of them out of the map and was a bit worried I softlocked myself, only to turn around and see the block back where it initially spawned. There's a lot of what I like to call "fun jank" in this game that I really like seeing in games that play with space like this.
