About
A puzzle about sorting slimes that got mixed up in test tubes.
- Two taps is the whole game
Tap a tube and the slime on top lifts out.
Tap another tube and it flies over in an arc.
It only lands on the same color, or in an empty tube. That is all.
- Same colors move together
A run of the same color at the top lifts as one.
Three stacked means three at once, so how many you can carry changes.
Working out the order to untangle them is the puzzle.
- Stuck is fine
When nothing works, watch a short video to add one more tube.
It does not guarantee a solution, but it usually opens a path.
If you run out of moves, the button quietly starts to glow.
- Go back whenever you like
Any stage you have cleared can be replayed from Select a stage on the title.
Your progress is never lost.
- The slimes talk a lot
Every few seconds one of them says something to itself.
"so hungry", "want pudding", "what is time".
None of it has anything to do with the board. There are 111 of them.
- How it looks
The slimes wobble all the time.
Lift one and it droops. Each color has a slightly different shape.
A tube sorted into one color looks pleased with itself.
Clear the board and you get fireworks, party poppers, or confetti.
- How long it takes
One board is about one to three minutes.
More colors and more tubes as you go.
Stop anywhere and it picks up where you left off.

Sound on is recommended. Every effect was made for this app.
There is no background music, so it is fine in a quiet room.
Japanese and English are both supported, and you can switch
between them any time in Settings.
