Yes, I plan to continue with the game, but not right now. When I finished the game I felt like I needed some fresh ideas, think about something else. Besides that, my artist is not available right now because she is in intensive studying. But yeah, I will add some stuff to the in the near future =)

I decided cocos2d over cocos2d-x because at time I was using objective-c in my job, so I could use some extra experience at the language. This decision was very helpful actually =)
And at time was not worried about multiple targets. But after it was done, some people came to me asking a Android version. Then I realized that now a days it is fundamental to target the game to multiple platforms. So I will definitely look cocos2d-x, it seems very nice to use too =)

Of course, will be glad to..
Like I said, I develop this game to have a study case to learn Cocos2d and Box2d. At beginning I would not publish this at all. I mean, I'm a technical guy and don't know a thing about art or game design. When I finished the game core it was something like this:



Obviously, it was not good to publish. But, well, I had so much fun writing this game that I did not want to forget about this project. So I looked for a real designer, so I can hire to make something beautiful. ( Amanda Duarte - http://dinduarte.com )
But when she asked for me a bunch of stuff about the game I did not know what to say yet, I didn't really have thought about this things, like the theme or the main character. Until that moment I just thought about the mechanics (my mistake). So it occurred to me that would be nice if the world was made of paper. And it was what I asked: Origami world.. I think it worked to this game =)

I know it is not the most exciting game yet, but I really had some fun doing it. And the objective was reached: "Know the tools to the next exciting game".
