My marble popper style game is getting close! Here's my very short preview video of Blackbeard's Blast.
I started working on this over 2 years ago before v3 beta even came out. It uses the latest version of cocos2d v3.49 and yes lots of spritebuilder (mostly just for UI stuff). Why did it take so long? I went through several periods of burnout, and I only work on it nights and weekends. I hope to soft launch in the next few weeks.
If anyone wants to do free testing for me (ha!) or just try it out send me your email and I'll send you a testflight copy.
