Not that good
I am designer and I found that the lil elements on the game ui are crowded and not placed well. You must consider primary elements and secondary elements. Currently every elements are at same priority. Too much side tasks like cards, levels, upgrades, etc. what if gamer want to enjoy only run??? I installed it because I was impresses with the clean graphics. I am uninstalling because of two things: Ui is not good Too much side mini activities. Suggestion: Make a mode for those who want only run, but yes you can keep your revenue model. Check candy crush and other similar games with side mini tasks for gamers. Those apps are not crowded with every element highlighted equally. Keep only primary actions highlighted. One more thing those bubbles comes out of bag are I think png files, they are not with high quality. Similarly I saw same issue with some other graphics.
