itch.io

What  I meant was that I don't know how to open the game. I found a file that says game but I don't know if i'm supposed to press something

I got into the DemonRiseUpDemo file and found a game file but I don't know how to what to press to play the game. Do I have to use the terminal? Also sorry i'm bothering you so much.

Everything is there (probably?) but since I don't know much know much about Linux  I don't know how to run it

How do I run this on Linux?
