$15.99Shift Happens Swap size, throw your friend
Two connected jelly blobs, Bismo and Plom, swap size and weight at will. You and a co-op friend throw each other, trade bulk to solve puzzles, fight over coins, and wobble through 40-odd handcrafted levels across labs, forests, canyons, and cold caves.

Swap bulk, toss your friend
One of you goes big and heavy, the other goes small and bouncy, then you trade in a second. The big one holds down switches and smashes through, the small one jumps higher and flies farther when thrown. You toss your partner across gaps, catch coins, and occasionally toss them somewhere unhelpful just because you can. Backstabbing and taunting are practically part of the controls, and fighting over coins keeps every crossing honest.
Four worlds of co-op puzzles
You start in the freaked-out lab where Bismo and Plom had their accident, then head into overgrown forest, dry canyons with deadly wind, and bitingly cold caves. Over 40 co-op levels mix platforming, timing, and coordination puzzles, with extra challenges and hidden rewards for completionists and explorers, plus 8 unlockable bonus levels and time challenges per level. Solo co-op friends get 30-odd separate single-player levels built around juggling both blobs yourself, a much harder multitasking puzzle.
Good to know?
Can you play it solo?
Yes. There are more than 30 single-player levels with different content from co-op, where you switch between both creatures yourself. It plays like a harder multitasking challenge, while the co-op campaign is built for two, local or online, with gamepads recommended.
How do the size-swapping puzzles work?
Bismo and Plom can exchange size and abilities at will. Bulk changes weight, jump height, and how far you fly when thrown, so one holds things down while the other reaches high ledges or rides a good throw. Later levels and bonus stages demand tight timing and quick swaps.
What is there besides finishing levels?
Levels hide extra challenges and rewards for explorers and completionists, collectibles that unlock 8 bonus levels split between solo and co-op, and time challenges for each level. Coins scattered through co-op stages double as another contest, since you can grab them or steal them from each other.
