You're beans. You got eaten. The bottom of the stomach is acid, and enzymes and bacteria want you dissolved. Survive until the stomach burps, then ride the gas straight up the middle and out the top.
Every time you get out, something else eats you: Uncle Gary, then his dog, then a raccoon, all the way up the food chain.
Get digested and you come back as a different bean. Every bean plays different. You're supposed to work together. You're also allowed to shove each other into the acid.
If everybody gets digested at the same time, that stomach starts over.

Land on enemies to squash them. Grab a friend out of the acid to save them (or throw them in). Being carried? Mash jump. Throw the antacid into the acid and it goes down. Pause: Esc, P or Start.
