I assume this is oGame or similar? When I was in high school I had a lot of fun learning Javascript/HTML in the console & TamperMonkey to create shortcut menus, faster actions, track area activity, etc. The modern versions of these use a lot more Javascript for countdown timers, and while that's nice the pages usually feel slower.
