Like many here, I've been using C2 for quite some time, and I think it's a fantastic tool! It helped me to get started as a game developer, when I just didn't have the knowledge or experience to try more complex game engines.
Sadly I've come to the conclusion that I need to move to greener pastures for now. Unfortunately I've been hearing the same old excuses week after week... month after month, since I started using C2 some 3.5 years ago. And for a while I kept hoping the improvements we needed were just around the corner (as promised). But the same problems I experienced when I began using C2 (poor performance, lack of robust 3rd party wrappers etc.), still persist. Despite the many assurances we constantly see in the forum.
I know things have improved since the early days, and I realise it can't be easy when you have such a small team. So the developers have done a superb job under the circumstances. But unfortunately the main issues preventing us from releasing high quality games on mobile (with good, consistent performance), are still there. And sadly I don't see this changing any time soon.
I truly hope the developers can prove me wrong, and turn things around. And I'll still keep an eye on all things C2, dropping by every now and then to see what's new. But for the time being it makes more sense for me to focus on learning to use an engine that will allow me to create the games I want, rather than forcing me to curb my expectations.
