Are you able to activate this for the itch.io app I don't remember if I tried this game once already or not. It seems to have an installer missing or something if I look in the download part. Sorry I'm tired ignore the last bit.
What do you mean by activate here? The 10 $ build basically has everything the premium one should and the free build has the base game with all its content.
Click on learn more about this warning and it should allow you to proceed anyway with it , Not sure why yours specifically is showing this as it's working fine on my mac and pc both.
