This is one of THE most creative puzzle game concepts I've ever seen, and it's also quite brutally difficult in a good way! It's so simple but the inherent concept is so clever and the minimalist presentation adds to that a lot, I'm just really impressed with this.
I'd be very interested to see a walkthrough of how the levels are meant to be beat because I definitely got stumped a few times and I think some solutions I found weren't the intended ones
Fantastic work!
