One thing I will say as a new user with not much experience with C3 is that I rather like all the quick patch releases and updates! I think Scirra should be congratulated on that alone, as many of these types of engines have rather slow releases and updates (Game Maker Studio and Xojo to name a few).
I haven't really dug into making a game in C3 yet, but I know generally if there's a reported and confirmed bug in the engine itself, it'll more or less be fixed within a short space of time, guaranteed.
