Absolutely fantastic puzzle design here, I'm not sure if I'll ever understand how people make these puzzles after coming up with the mechanics. I had a great time figuring them out but I can only take so much of these kinds of puzzles before my brain overheats...
Visuals aren't anything super special but it's the right choice for this game for sure. I personally find the CRT shaders people get online to usually be way too strong but it's not too bad here. My main issues were that I wish I could move the guy a lot faster and that the music got a little repetitive, but it was no issue with those puzzles to entertain me :)
Great work!
