This game is seriously good fun! The concept is pretty simple. Catch the blobs as they drop down the screen and avoid the mines. If your blobs touch a mine they are lost. The trick is that as you collect blobs they stack-up on-top of each other. And as you move there's a slight delay in them following you, so you have to be really careful to angle them just right!
When you see a UFO hit it with your blobs and they'll all be saved.
There are different types of blobs as well, some give you a shield, others slow down time and some even blow-up the mines.
Simple but great.
