Innersloth updated the way that the Among Us downloads work. They used to have an optional payment, but it was $5 for the PC version. Now, the "demo" is Android, and the paid version is for PC
In short: The Android version of this game is completely free on the Play Store, while you will have to shell out $5 for the PC version, for some reason.
$5 is nothing, but still. I guess its to support development.
