Currently beta testing on itch.io and Google Play

ℹ️ Fill the board with tessellating jelly-ominoes to earn points.

ℹ️ Control the descent of each piece and its rotation to line them up perfectly.

ℹ️ Keep an eye on the Jiggleometer - pieces must be settled to get deleted!

ℹ️ if a piece goes over the top, it's game over. Clear pieces by filling rows, and keeping the Jiggleometer low!
