Thanks for the in depth feedback. This helps a lot. A few people already said that we need a counter for the cars that are still left to play...which really is needed. I also like you suggestion that the clarity is displayed as orbs that move over to the counter. Would make things easier to read. That's our biggest issue I think. The concept is quite tricky and we have to find better ways to visualize it.
On the illustration side it is also a thing that the smaller ones on the cards are not distinct enough. I understand that you don't like them altogether, but I am not sure if replacing them by colors/shapes would make it that much easier to understand, makes it even more abstract.
Time constraints are your biggest enemy when it comes to a game jam......but I think we learned a lot. Thanks for your long feedback.
