ummm Chromebooks can't run Windows executables which is what among us is for so you can't play it sorry
I mean, most chromebooks have play store, and I use my chromebook to play the android game, so maybe talking about the play store version
but OP said he BOUGHT it which most likely means OP paid for it on Itch because the Play Store version is free and you don't have to buy it. Just a thought.
