At Jam half-time, lets get a thread going for screenshots. I'll start (fresh from today):
I used multicolor and the gun image manipulator program to make a title-image for my game; unfortunate that tic80 supports loading a screenshot on to the cart but that the runtime doesn't seem to have access to that, it has to be embedded as code so i'm bumping up on limits with both copies. i suppose multicolor has an RLE that i could translate to fennel if i start bumping up on cart size more than time and ambition ...
