There is a "you win" screen or i did something wrong?https://imgur.com/a/eM9AYzM
There is indeed a win screen. You have red and yellow regions that are each 4 tiles big, as well as brown and green regions that are each 5 tiles big. Every region has to be a different size (as measured by number of tiles).
i misread shape for size and now i feel dumb, thanks
