(Edited.) I just played your other game Nub city - I like that style!. Also if you give them some funny examples of things to draw, e.g. a butt (even if not in the game) I think it would get people clicking.
Yeah I used a different tool for nub city, it just takes a lot longer to make the art that way which I didn't really have time for since this was just 48 hours, whereas nub city was 10 days
