Ah, thank you everyone. I missed your replies! They're heartwarming !
nikosurfing: I am waiting for webGL in the browser to spread on mobile devices before that. I would like to embrace an online freemium model, and I'm waiting for phonegap to be really thoroughly tested by other C2 users. I'm a game designer first and foremost, so I'd rather not spend too much time bothering with technical aspects such as rendering limitations and lower level elements too much.
In the meantime, I'm stopping my activity as a freelance game artist, to dedicate all of my time to game design (be it for clients, with collaborators...).
Anyway, Dan will stay paused for a little while still. I'm working on some simpler casual game for a publisher at the moment. I'd like to tackle some simpler projects before this one: I don't want to mess up with the kind of complexity it requires overall.
