I have no problems about mentioning that game made using cocos2d, but was thinking how to do that properly.
I wasn't planing to add some kind of "credits" screen to the game so the only place i can credit cocos2d is loading screen. Now the problem is how to not over do it. If you place cocos2d logo, game logo, your company logo and colorful background there is way too much info on screen. Other problem is that end user might confuse your company logo with cocos2d logo and think that its made by cocos2d.
Maybe i should just write "powered by cocos2d" lets say in lower right corner without logo?
Or maybe mentioning on iTunes site that game using cocos2d and not mentioning it in game is better idea? (CocosDenshion license says nothing about it)
Any thoughts about that?
