Hello! I am now developing a party game for up to 8 players with cocos2d-x. 4 of them can control characters using on-screen controllers, others can connect with their iPhones as controllers. This is the first trailer of the game: http://www.youtube.com/watch?v=D7-6gL-_klQ
I am using Particle Designer for explosion effects, Glyph Editor for embedded bitmap fonts and Texture Packer for optimizations of sprites. As CocosDenshion lacks a lot of features on C++, I am using BASS for sound and music playback.
The game will be released on AppStore at the start of 2014. I hope you like the trailer video, if you do, follow us on twitter: https://twitter.com/runiongame
