If you’re eating, you might not want to read this. In the flash game I’m about to link you to, you control a little creature that looks a bit like Kirby who uses vomit as a projectile. Chuck up in one direction, and you’ll be propelled in the opposite.
In some cases, you end up in pits that need filling up with puke before you can swim out. Other times, you run out of chunder in your gut and have to ‘fill up’ by eating barf left by someone else before you can continue.
