Thanks for playing!
I try to make jam games lean towards funny because, atleast in my case, they tend to end up a bit clunky... I have a few hours to spend even in the time frame of GWJ.
Some colors are a bit "fancy" in that they require an extra card. So you have orange which is red/yellow. But there is also red-orange which requires an extra red. And gold requires red/yellow/yellow. These are not intuitive enough :D I thought of some extra features to assist but time was not on my side.
