WHAT YOU DO, STEP BY STEP
You play a soft green blob that is trying to get out of a dangerous facility. Each room is a small set of platforms and hazards, and the blob stretches and squashes as it moves.
Move with the Left and Right arrows, jump with Up and drop down through a platform with Down. Sharp spikes are the main danger, so watch where you land.
Floppy disks are hidden around the rooms. Collecting them is optional but gives you a reason to explore instead of running straight through.
HANDS ON THE KEYS
TIPS TO START WITH
- Look at where the spikes are before you jump, not while you are in the air.
- Use the Down key to drop through platforms instead of walking around them.
- If a room looks empty, check the corners; floppy disks are hidden.
- Short, controlled jumps are safer than long ones, since the blob squashes on landing.
WHOSE PENNANT THIS IS
Players who enjoy classic platformers with a bit of exploring, and anyone who likes a game that is easy to learn with arrow keys.
THE FINE PRINT, HONESTLY
- Poki shows ads around its games, so expect some before and around the game.
- Spikes mean you will repeat some rooms, which may frustrate players who dislike trial and error.
