I love this game!
You might want to think about color-blind players, though? And even those with poor monitor colors. If you're truly attached to the color scheme, adding a text label on-focus would go a long way for accessibility.
I'm not colorblind, and telling the colors apart slows me down.
Also noted: flushes, like patterns with all the same color, are not rewarded. I got 4 doors of all colors = 4 points. That does make sense for the gameplay! Since we're building houses. But it's more difficult to draw 4-of-a-kind, so a heads-up would have been helpful.
