Wow, this is really fun. My jaw dropped when I saw the hint about being able to laser yourself! It didn't even occur to me that it was an option, and I love that it's a thing.
Also, this is a really good example of how to introduce mechanics to a player without any explicit tutorial (other than the controls). The final puzzles of each section and especially the last part of the last one really made me feel smart while also giving a little challenge. You could totally build on this if you wanted to, and y'all should be proud of what you've made!
