I don't know if the same applies to Chromebook, but here's the steps:
Make sure to download the file that says "mac" in it. you'll need that specific one on apple products.
when you open the file, find the type labeled "application". If it gives you a warning, hit the "ignore" or "run anyway" option. you may need to extract the files first for it to work properly.
Once extracted, another file tab should open, and you'll see another type labeled "application". That's the game.
If it gives you another warning, hit "ignore" or "run anyway" again and it should open the game. Have fuuun!
