If you install the linux version of itch, then it won’t work since it’ll look for the linux version of the game. You have to install the windows version of itch client through Gaming mode, then find the exe file of the client and add it to Steam as a non-steam game so you can run the client through gaming mode. This will allow you to install windows version of any game, including Kemo Coliseum.
I’m not sure what you mean about discord. We do not offer any discord reward.
