We've updated the game to the latest Unity engine 4.X version (4.6.8). This will address various platform specific issues (input, controller detection etc.)
For those who have controller issues:
You can customize your controller setup in the input window pre-game.
To open this window:
<*> On Mac: hold the options key while starting the game to open the setting dialog
<*>On Windows: hold the options key while starting the game to open the setting dialog
<*>On Linux: Add to the games launch options: -show-screen-selector
v5 Minor gamepad update
Due to community request we've made a small update: The default gamepad controls are now more sutiable for a race game (no more automatic forwards movement when using the left stick)
To spice this post up, here the first cool GIF i found on the community hub ;)
