There's a big tension around recently due to many recent bugs and old problems/topics as well. I am also frustrated as I'm trying to release my Android app which is finished, but both CocoonIO an IntelXDK have some unacceptable issues now.
Believe me I had moments I want to cry as well... but if you calm down and look at the big picture, then after all it's not C2 which is a problem. It is true that Ashley could have made better decisions sometime as megatronx mentioned, but well... that's another story.
Regarding that C2 is a "product which is supposed to do what it says on the box" I must disagree a bit. Software is not a bike. You can say that about an easy accountant software which needs just one update a year to adjust new tax rules, but not about an engine which is made to make other software. Thinking this ways you should have the version of C2 which you downloaded as first, and use only wrappers and everything around with the version which was available the time you downloaded that first C2. Then it would be what was on the box (at that time).
But we need/want more all the time right? This technology is extremely rapid. New things come out and we want them in C2, so we have updates and what goes after - issues which need some fix.
Let's be honest... even Microsoft and Googe make soft mistakes and they have a series of quality checks.
After all I have really mixed feelings, cause from one side I do understand the software production system and it flaws. But from another I am also tired of "hoping" that "they" will fix "it" soon.
I wouldn't judge anyone for dropping C2. I know sometimes frustration reaches the limit and you simply say "ahh f*** it!". Moving to Unity or something like that would probably give you better performance and feeling of stability, but surely development won't be that fun as with C2.
Personally I told a friend today that this is my second and last mobile game with C2. I'll be following IntelXDK and CocoonIO and wait for the good times (I'm sure they will come within maximum 2 years). But I'm absolutely not leaving C2. Let's face it. It is the best HTML5 game engine in the world.
P.S. Wanted to write some short thoughts just to follow this subject, but as usually I wrote ten times more than I planned (laughter through tears)
