I thought I had the October Challenge covered put an existing game up for it that is already earning money and make it for charity!
Cancer Wars is on Kongregate
And to date for this month it has made $0.35 from 207 ad supported plays so I only need about 389 new plays to earn that 1$ this month!
Please play it here http://www.kongregate.com/games/Arowx/arowx-cancer-wars-v0-5!
Because cancer effects 1 in 3 people and all revenue goes to a Scientific Cancer Research Charity!
