just to let you know.

In order to piss yourself while playing this game, you first need to set a challenge in order to fail it and make urine spill out of your pants, and maybe on your bed. I recommend choosing 50/20 mode for this occasion so that it'll be easiest to excrete fecal matter. However, if you want to piss, ♥♥♥♥, AND ♥♥♥, you'll might need to choose the easiest challenges to win, and try to fail them. Easy challenges are actually far more difficult to fail, but if your a beginner i'd recommend 50/20 mode again.

"How does failing this game make me piss myself, Dr. Spaghetti?" You might be asking. Well when you fail the game, one of the 50+ characters in this game, when triggered, will attack you in a animation of shaking violence. The setting behind the character attacking you will shake like the Californian earthquake. During this animation, a scream of that character will play at the start. This animation + sound effect is known as a Jumpscare. Jumpscares are scientifically proven to make the genitalia excrete either one or both penal fluids depending on the scary scale of the jumpscare. it will also make the victim of the jumpscare extract waste out of its anus which also depends on the scary scale of the jumpscare. This is a crucial step in the pissing yourself process.
