A really nice idea, however the execution? Well not so nice. The gameplay is too slow if you haven't noticed in the build. You have to collect coins to buy items in the shop, 50 coins an item. Coins spawn at an exceedingly slow rate (I know about the "5xC") and the obstacles fall at a really slow rate. However, you finished a game, and that is all that matters. You will improve over time, you know how they say: "Trial and Error". Have fun game making!
