Thanks! Yeah, the display on the PocketCHIP isn't that great, but in general it might be nice to have a color blind accessibility feature. Since it's hard to figure out a system that works for red/green and blue/yellow color blindness (the game has lots of auto-generated color "schemes"), maybe a simple "color blind" toggle that will somehow modify the tiles or something could do the trick...
As a quick workaround: In the title screen, you can use the up/down arrows to pick a color scheme. You can use the "Loonies" and "8192" text to sample how the tiles will look like, so you get one that is easily distinguished. Of course, as you progress in the game, the color scheme will change again, but it should make it more enjoyable/usable at the start of the game.
