Hi Sharm, thanks for your response.

Reading back my post i noticed that nowhere did i mention that the game itself would be totally free. I mentioned the accidental revenue because there are some gaming websites that share part of the advertising income with game creators (like kongregate.com does), so that's why i put that in there.

Right now i'm completely blank in terms of art style or even a theme.
I thought it would be nice to offer up the chance to a participating graphics artist to really 'go to town' on this game and design a theme and use a style that he/she would like to see herself.

I'd much rather work with someone who is passionate  about the job at hand, then having someone make artwork exactly the way i would like it and maybe be less motivated.

So there's quite a lot of freedom (but also quite some work) for someone who is up for the task.

I noticed from your profile you're into pixel art, which would be a perfectly viable style to use for this game. Only exception would that the end product would be a pixelated effect (original artwork being scaled up to fit the higher resolution) unless one would be willing to torture themselves by creating hi-res (800 x 700 or so) pixel art :)

I'd love to hear if you're interested.
