Hello. I am new to computors and cant run the game file given here. I play instead on coolmathgames and was wondering if that has any major downsides runwise?

theres a tutorial that max made in guides that shows how to get the files working, but if you really need to play on browser go to redball17levels.com and set your date back to before 2021 and it should be working

OK But the reason why I cant do it is not only that i am new but I am on a school chromebook. Why didnt i say that before? sry.

Coolmathgames has a few downsides for speedrunning, because they literally changes the games. An example is The World's Hardest Game because the whole game was changed, and also another example is There Is No Game because they removed the language option at the start, therefore the run can't be started. I don't know about Red Ball 4 though, might need to look into it.
