To answer your questions in the conclusion section:
Yes there are two exits, if it were a full game each would lead to a different starting point on the next level. I will make that clearer for the playtest with some additional text at the end.
I haven't had a chance to watch the full playthrough yet (I absolutely will), but if you didn't exploit the engine (force yourself through a wall or something) then you didn't cheat. I wanted it to be non linear. Sometimes there are sections with very easy bypasses, and I learned while making the level that it's ok if there are easy bypasses for more difficult challenges, because the player usually enjoys the solving/feeling clever part moreso than engaging with the intended challenge.
Thanks again for your time! I'll check out your submission and give a playtest video back. (I believe you said you participated)
