Over the weekend we worked on an update to make the game playable on Mac as well as in the web browser (embedded on the main game page). 

Web browsers do not automatically support all controller types, but it has been tested in Chrome with XBox controllers. If the web build doesn't work with your controller, we've left our debug hotkeys on to allow keyboard controls. 

A -> (A) (for character select and confirm/continue)

Space -> Jump/Boost

Arrow Keys -> Movement

Left Shift -> Shoot (no aim on keyboard)

J -> Skip to next level
