Oh my gosh. I feel so dumb. I'm stuck on level 2. I know I must be missing something obvious, but I can't figure it out.
If you aren't used to block-pushing puzzles, level 2 might be tricky- it's stumped several other playtesters so I'm considering removing it. Movement pattern is: >^>^>>^>v>^>>>
I see where my error was now. I thought I needed an additional key segment, and so would reset every time I couldn't reach the key fragments
