Well designed, simple, fun. Good way to build an ecosystem with a simple intuitive interface. Difficult to think of a way to monetise, but 'cool' has a way of defining its own ecosystem.

Interesting concept for a game, I like that you seem to have come up with a somewhat unique (in terms of a game concept). Could be a cool game if developed, looking forward to seeing where this goes.

Nice design - can you make it addictive?

Drawing game - multiuser . Not very compelling. No revenue model and limited differentiation IMO.

cool idea for a game, could do multiplayer match up. Be interesting to see how this goes.

Not focused on the SMS play...

Cool gamification. I like the design and the idea. What is the business model? marketing? etc...
