This is really juicy for something with such basic graphics. Made it through 5 rooms, gonna get onto the remaining rooms later. It's very fun, the core puzzle mechanic and design is solid af.
Don't have any real complain, only thing that I could comment on would maybe be to change the order of the rooms.(?) I had a much harder time on the first puzzle room than on the rest (the other 4), but it was a good introduction to the anti-materia square.
Great shader work btw.
