I see, can somebody else help with this matter then?, mint cinnamon is similar to ubuntu in many ways, the problem i am having is that i have nothing that can understand how to run the main file here, there is no extension or association to begin with, it is just a file named ¨The Second Circle- A HellTaker Fangame¨
