Gen is all about guiding a bunch of spheres to a bigger sphere using the mouse as an 'attractor mechanism'. The balls of light will follow the mouse pointer in a swooping sort of way, so it's your job to make sure they don't swing about too much and destroy themselves on deadly surroundings.

The game also has simple physics-based puzzles going on too, so your spheres need to be dragged into obstacles to barge them out of the way. Cue spinning wheels and cool-looking contraptions.

With 20 levels to work your way through, Gen is the perfect puzzler for a bit of time-wasting. Check it out at Armor Games.
