I really liked this! I finished 30:37 with I think full green boxes? I got 7 of them. I really enjoyed the puzzle aspect, although some parts were a bit confusing and I had to rely on the walkthrough for it (like the teleporting - I got to the z + -> room so I was confused when i had to press the up arrow and not z + right arrow). It felt like something I would play on Cool Math as a kid :)
