Loved everything about the art of this game; from the characters to the UI, it's all very pleasing. The UI in particular is very clear and easy to read.
It took me a bit to get my head around the concept; when it states the idea is to get sets of cards, I assumed my goal was to have a massive hand, however handing in a set still feels like you're emptying your hand. I'd love to see a way to utilize and maintain a large number of cards in your hand to emphasize that reversed Uno concept.
I love the option to Steal, good odds balance for how powerful it can be.
