Mario Games

Mario will run and run and keep on running some more. All you do is tell him when to jump. This endless runner game is a lot more than just timing your jumps and running forever though. It's got upgrades yo! You earn experience points as you run and you can spend them after each death. Upgrade things like jumping power or acceleration or add new powers like the ability to double jump (I highly recommend this one). The extra depth of having upgradable abilities is a nice touch.
