Quite cute! It was honestly quite exciting to figure out how the game worked and what all of the buttons do (...took me more than I care to admit to figure out where to draw from the deck), but if I had even a little bit less patience I would have dropped it before figuring everything out, so maybe a better explanation and/or some on-screen arrows and text would help a lot.
Also, sometimes you get stuck in a position where none of your cards have a shape you need, and while I figured out how to always get the color you need, I couldn't do the same for shapes, and doing the whole wheel process over and over banking on a random drop can get grating.
