What happens in play
You play a soft green blob that stretches, squashes and jumps through rooms of a dangerous facility, trying to get out. Spikes are the main hazard, and the rooms hide floppy disks to collect.
Left and right arrows move the slime, up makes it jump and down lets it drop. The stretch and squash of the body is part of the game, so jumps feel different from a rigid character. Poki lists computer, phone and tablet.
“Look through each room before leaving it; the floppy disks are hidden.”

Tips for the first runs
Look through each room before leaving it; the floppy disks are hidden.
Use the down arrow to drop onto a lower ledge instead of searching for a way around.
Time jumps over spikes rather than holding the direction key down.
Treat the slime's stretch as extra reach when you plan a jump.

The kind of player it fits
Players who like platform games with small rooms and a collecting side goal.
Where it can frustrate
- Poki does not state an age suitability for it.
- Poki is an ad-supported platform, so expect advertising around the game on poki.com.
- Spikes can send you back, which may frustrate players who dislike repeating a section.
