I don't know, I put it to download on my pc and it works for me. Unzip the folder with WinRAR or 7Zip, then leave an executable called SquidGame.exe and that would be it.
yeah i extracted it and now its working, but i cannot even move when i launch the game... needs a ton of work, sucks because i really wanted to try it but when i spawn in my WASD BARELY moves me.
