Dust Heap Survival

Move the heaps onto places with dust so they get bigger. Avoid them getting sucked in by the vacuum cleaners. Make two out of one by clicking on one and pressing the left and right arrow buttons after another several times. You can only make new heaps when the heap you are on is big enough. Complete 40 levels, 10 for each vacuum cleaner, by having the necessary amount of heaps in the level. Press space to restart the level, press enter to go back to the menu, use the down and down arrow keys to turn the sounds off or on and press the right mouse button to turn full screen mode off or on.
