This game is a PICO-8 showcase!
I just donated, please do one more fix so it no longer crashes in version 0.2.1B. Since zep promised the API is now stable that hopefully means no more updates necessary.
The version on the BBS/splore doesn't crash for me on PICO-8 0.2.1b. Can you screenshot the crash?
I think I can almost replicate the error. It seems to only appear when I have the cart saved locally by favoriting or saving it and not running directly from splore. I open the first door and walk left to the machines and then back. Then this message pops up.
