Good concept, wrong aproch.
Things to fix;
1. The name, The name wooglings is chidish and stupid,
2. The characters, Little squarish blobs just don't apeal to most people try something different.
3.The game play, having them continuously move across the screen with no way to control them makes the game boring, also try having the little tool cloud pop up as a bar in a corner.
ps. make the game harder and add in a twist of puzzle.
