description
A puzzle-game where you place blobs on a playingfield. The blobs have different colors and lines on them and by combining them well you can make them pop away, giving you points and "bla" preventing the board from filling up.
The game is actually quite hard to explain, but don't despair, there's an in-game tutorial.
