About This Game

From deep, dripping caverns to a skyline at night, join the slimes as they make their way through the dark.

Help them match with their closest friends, and as their journey goes on, they'll start moving into your terrarium.

Slimes Move as They Please

Slimes move in any direction, driven by instincts to move toward round objects, and away from diamond-shaped objects. Slimes turn toward whatever's pulling them, but a big enough chain can carry them somewhere else entirely.

A Glowing World

Follow the slimes' story as they explore a bioluminescent world where it's always night, from ancient forests, to a lounge above a city.

Leave It Open

Make a terrarium for your newfound slime friends while you work, watch TV, read, whatever it is you're doing. With decorations, sounds, timers, and a transparency overlay, customize the terrarium for while you're doing your own thing. They'll keep vibing. 

The Slimes

There's 8 kinds of slimes, each with their own personalities. As they move into your terrarium, watch them interact with each other, and the toys you leave out for them!

Endless

Want more puzzles? Endless mode generates boards forever, changing the difficulty of the boards as you clear them. Run out of moves and it reshuffles, keeping the board you're on, and the progress.

Stay A While

Meet your new slime friends, spend time relaxing with them. Get to know each slime's unique personality, while spending time in a "dark mode" style world, complete with glow and relaxing ambient music.
