The game does support keyboard controls but fully supports a connected game controller, we actually recommend that you play the game with a controller instead of the keyboard.
Besides the unique theme, we have implemented the concept of multiple lanes. This allows a player to transition between lanes as well as traverse the course forwards and backwards as they see fit.
The game has been released on Steam and can be purchased through that channel. Please visit http://store.steampowered.com/app/552370 to get your copy.
The demo is fully featured and the main difference is that the demo only has 3 levels, a minimal amount of visual upgrades.
