Heya! The core concept was super cool. Line-of-sight stuff is pretty nifty.
I found the controls a little bit confusing. Spacebar isn't jump, it resets you. And not only that, but it resets you to the first puzzle which can be frustrating if you get further on and subconsciously try to jump. I got stuck on level 3, and couldn't figure out how to get the exit to move anywhere else :(
Nice job!
