Spy Racing

A nice little timewaster, you drive on an endless highway, constantly avoiding other cars (or, if you've got the upgrades, simply ramming them to make them disappear).

Mostly you'll drive left and right, but you can move forward and backwards a few meters as well. The objective is to not crash and gather up as many disks as you can.

The disks you collect remain yours even if you crash, so if you drive for an hour or repeatedly for a few minutes, you'll get to keep what is yours. Until you spend them to get cool upgrades, of course :-)
