1SlimePlz by Saran Siripuekpong

 1SlimePlz  comes from Saran Siripuekpong.  The object is to tap on an empty square which is adjacent to 2 or more slime objects and watch them merge.

Ideally, you'll want to end up with just 1 slime pile and hopefully it will land on the star.

40 levels - they go fast.
