Graphical issues make the dungeon seem like a fun-house mirror hallucination, which is mostly unplayable. The cut scene dialog is a nice touch, but is so slow that I wanted to skip it. The themes are entirely missing.
In Chrome in Windows I can see all the cubes of the world, including the blackness of the other spaces across the whole map, piled on each other. It's like weird psychedelic x-ray vision.
