wait, can you make offline game, For example. hardware tycoon/processor and eaglercraft and others boring game with no multiplayer loaded doesn't require wifi. If big tech doesn't have any multiplayer, then why big tech require wifi?
The game does not require a constant WIFI connection, it only needs WIFI to load the game. On browsers, the browser cache will get cleared either because you opened a lot of tabs or because your computer ran out of memory. Regardless, the game needs to be reloaded, which requires WIFI. That's how every browser game works really, unless they are built in a way that stores the game files for offline use, but I would think that's quite rare and has its own problems.
The game will have a Linux version in the future. However, as you mentioned, you run the game on a school computer, which means you probably can't install any apps on it because of admin privileges.
