any ro/bro/ know how to come down from a high quickly?
There's nothing I know of you could take to end it but you can drink a cup of coffee and either go run a couple of miles or do some kind of manual labor and it will wear off faster.
Go to sleep, or watch your favorite show. Water, food, something like that
It's a game where you "surf" your own personal music and hit colorful blocks. It's only fun when you're high. My friends all used to know when I was high on steam when I smoked a lot a few years ago.
