I'm glad you gave it a shot, but I'm sorry you had that experience.
For M1, I was referring to the Left Mouse Button, and the semicolon was specifically as it was. I will consider your suggestion to maybe be able to remap some of the buttons.
The convey belt was an issue that I'd tried to look into but couldn't fully fix, so I'm also sorry that you had that experience.
I'm still hoping you enjoyed the game and narrative, and hoping that the small bugs and inaccessibilities didn't completely soil your experience. Cheers dude!
