I wanted to like this, but having to know ahead of time how to avoid softlocking yourself and needing to restart the game over and over just isn't a good game mechanic. Even knowing exactly what to do, the game keeps crashing around 15 minutes in before I can get to the hidden layer. On this last attempt, I had just used keycard 7 so only one door remained, but for some reason I was able to partially walk through that final door and get stuck inside it, and there doesn't seem to be a way to reset my position without restarting the game. If there were more quality of life features to prevent the need to restart over and over then I'd like to play the game to completion, but as slow-paced and clunky as the game is I'm going to give up.
One time the game crashed I was just walking along as usual and the PICO-8 window froze and became unresponsive. I couldn't even pause. I suspect it may have been one of those collision adjustment infinite loop bugs.
