First, tap the Enable Touch Controls on the bottom left of corner of the screen. Then you can swipe to move. Every third step you take, you will launch a ball of goo in that direction. If there is no space for the goo to travel, you'll be squished! Try to fill up as much of the board as you can without running out of space. Reach the target score to unlock the next level.

Each level also has a record score. Can you reach it before you get squished?
