if you have any suggestions for ways to improve the game jam, please include them here
With the exception for audio and questions about similar things with vibration and such, I think there's a better way to rule it that allows all this. The main limitation I feel you are going for in the jam is "One bit of output", and the rules about how to display the screen are just to enforce that. I think it would be reasonable to have as many different outputs as you like as long as these outputs perfectly match which colour is on screen. In fact I don't even think having a screen at all should be mandatory. As long as there is only 1 bit of output since that's what the jam is really about, "the minimum (non-zero) feedback that a game could possibly have."
Some examples of 1-bit output that I feel should be allowed (as long as they all match if you use more than 1):
I completely agree with your interpretation. I wanted to keep the list of rules short and simple, while trying to convey this idea as clearly as possible, but I know what I've written isn't necessarily the clearest. do you think I should change or add to the rules, to make them better convey what I'm going for? mentioning that using vibration or images (e.g. cat / spain) is okay seemed like a good way to confuse people.
Since the main thing is just 1 bit of output, can I let my game run in whatever resolution it wants, as long as I only draw 1 color or another (maintaining 1 bit of output only)? The reason I'm thinking to ask this is because I'm going to use LÖVE and I'd like to just leave things at defaults and possibly try porting it to Android.
Like mokesmoe said above, I think the jam rules should be reworded to allow any kind of output as long as it is on or off, 1 bit, no inbetweens.
"make a game in 1-bit colour, on a 1px × 1px display with no audio; the minimum (non-zero) feedback that a game could possibly have."
perhaps changed to
"make a game in 1-bit colour, on a 1px × 1px display; the minimum (non-zero) feedback that a game could possibly have. For accessibility purposes, you can replace using visual feedback with using audio feedback in its place, or any other kind of 1-bit, on/off feedback. You can even use multiple feedback methods in the game, as long as they convey the same, exact, synchronized information. (issue a beep sound at the same time you turn the screen color to 'on', then stop the beep sound at the exact same time you stop showing the 'on' color, switch to the 'off' color instead). Alternatively using different methods of feedback, like sometimes flashing the screen and sometimes beeping is not allowed."
