Read between the lines, they hacked the TNP source files.
Try loading some of the cap files into an editor some time to see what's really going on.
Construct is mostly an xml editor, a pretty darn good one at that, but the real magic happens in the runtime. Which is what they chose to dedicate their time to, rather than have some half assed attempts at making it work on other platforms like all the other so called cross platform exporters. Sure it's html5, but its the only one that gets it right.
What flavor *is* that kool-aid, I wonder?
I dunno about you, buy I make games to sell them, and I want to sell them in as many places as possible where people buy the kind of games I make. Construct seems to actively prevent that, despite repeated mentions - for years, now - of plans to support other platforms, as well as the features people who buy games expect on those platforms. End of story. Not everyone wants to make knockoff games built on purchased templates in a misguided attempt to generate money through mobile ads.
Anyways. Good on Aurelien for finding a way to bring his (pretty awesome) game to other platforms. Shame it had to be achieved in such a time-consuming, roundabout way, due to the misleading claims of the original engine's creators. Live and learn I suppose.
