— Games Do you have a game on Steam made in C2? Do you have customers e-mailing and commenting and posting reviews of stuttering and glitches that are out of your control? You keep showing up to promote how amazing C2 is to people who already know that C2 itself is an amazing editor. I've been using tools like it since Klik 'N Play, TGF, MMF, Construct Classic, and so on, and this is definitely the next step in their evolution.
But stop pretending that we can't complain just because the adverts don't define the words "professional", "easy", and "powerful". Those words have to mean something or otherwise my definition of a great game will have to be Flappy Bird, Candy Crush Saga, and Bejewelled.
As I said a few times, I bought C2 (and later bought the business upgrade) under the belief that it would surpass CC performance, and even that at some point in the past year it already had (based on the blog post), but after finally making a large game it has shown not to be the case. The demo doesn't let you get to the game size of a full commercial title like The Next Penelope (or the game Chris and I made, Insanity's Blade, a 500MB game inspired by 80's arcade games like GnG), and by that time it's too late to be able to isolate single issues (they all work together to drain the FPS), let alone for Scirra to wade through thousands of events, and tonnes of layouts and objects.
HTML5 has improved with the help of some WEBGL and asm.js/emscripten, so there are hopes for improved performance in future builds, but it definitely isn't a solidified platform yet so who knows what will come with changes to HTML5 itself (in 5.1 and 5.2 updates). Again, this isn't about native anymore, but about some sort of system where performance can be less of a mixed bag, especially across similar machines that should (in theory) be faster than my own development machine (but still have slowdown/issues), and in downgrading to Node-Webkit 10.5 it re-introduced audio bugs to make up for huge jank/jitter bugs.
