Journey to the center of this supermassive blackhole and find the Tesseract before you are...
Level difficulty feels a bit overrated here. This guy is easily checkpoint-able and outside of a few areas there aren't too many tricky 2 step cuts. Mostly a question of pathing.
Still a good level one section in particular is very good!
Spent a long time hunting for 2 more on one of the sections, but haven't been able to find it. Anyway, really enjoyable level (one part in particular I felt happy with the optimization) and nice aesthetic! Love the way the border looks.
Edit: Found 2 more! Thanks to Reach for sharing some checkpoints.
