Awesome! You should be able to see which keys do what in the controls menu as well, assuming the patch your playing has them.
It's not that I can't see controls - I can see them and also sense them, when they're imposed.
Like, if I set Player 1 to Key1 mode, and then find out that some button will pause the game, I can tell that menu navigation controls are still being imposed, even though every character is in Key mode.
A lot of developers want to include keybinders in their games. I'm not a proponent of that, because every new keybinder is something I have to learn, and the more of them there are, the more likely I am to run into a frivolous shortcoming.
That being said, when Pacman games gradually get better on Itch, I'll acknowledge it, and that has indeed happened.
