Man, I would love to try this one. Do you need/want help porting it to Linux?
A downloadable game for Windows
A first person mobility-based platformer, where you use various abilities to complete a course in less than 30 seconds.
Use WASD to move, Space to jump, Click to dash and Right Click to grapple (when unlocked).
Unzip and run Empyrean.exe
If the game does not start, do the following:
Go to: Engine -> Extras -> Redist -> en-us -> Double click on "UE4PrereqSetup_x64.exe"
This will install the DirectX prerequisites to run the game.
