The premise for this challenge was to create a Free To Play (F2P) game.

Driving games is one of my favourite game genres. Not to be confused with racing games, in which you race around a track lap after lap after lap.

A perfect example of frugality, Cursor*10 is a wonderful little Flash game, featuring time-manipulation gameplay. The game's objective is to reach the 16th floor. To go up one floor, click on the stairs. Click on pyramids to earn points. But on some floors, stairs are hidden, and you have, for example, to click two or more switches at the same time for them to appear. How can you do this, if you are playing alone and there's no possibility of pushing objects around? You have ten cursors.
