First of all, Thank you very much for your comment! That might just push me that extra tiny bit :), but now back to the important stuff. Can you tell me what doesn't work, or what error you get, then I'll be shure to help you and release a new version ASAP.
The error is:
"C:\The Optional Kind\downloads\CrossyRift\Engine\CrossyRift\Binaries\Win64\CrossyRift.exe"
CreateProcess() returned 2.
This is an error some people seem to recieve while starting Unreal Engine games. It has something to do with running commands for the wrong version of a pc (x86 or x64). I'll build new versions, this time for both systems. Try running both and see what happens. I'll keep you up to date.
Never mind I found the problem. I was using the wrong .exe file. I was using the .exe file in the /engine/CrossyRift.exe. Not /engine/binaries/Win64/CrossyRift.exe. It was all my bad. Ill post the instructions to open it correctly so no one gets the same errors.
