Had to skip a couple levels (one for coordination, one I couldn't figure out; but I didn't note which levels) but I'm thoroughly enjoying this. Thought I wasn't doing very well but I've made it to 39 so far.
Level 7's "hint" (you can fold along a glitch) was more distracting than helpful. I spent way too much time trying to figure out what that meant - the puzzle itself is very doable, but ... I still don't know what you mean by "fold along" means here.
Thanks for the suggestion. By "along the glitch" I meant "parallel to the glitch". I agree that the wording can be confusing here. I'll update the text and also add an optional hint in case people need more clarification.
