Here's hoping these bugs are sorted out within a month.

A lot is riding on this game (quit work, gamedev full-time), I knew it when I set out to build it. The deadline was this December.
This is why I truly hope C3 would eventually have a native export. We rely too much on the whims of 3rd party wrappers. I just want the normal reliance on Drivers & Engine to cooperate. Here we got the middle-man Chromium that just tries to Seppuku everyone all the time.
Ouch! Really hoping it works out for you but I don't expect Scirra to be able to do too much themselves.
Node-Webkit (and Chrome) is constantly holding Construct 2 users hostage every other update so far. We were lucky to get something that (barely) works and stick with it (R192 and NW 10.5) for Windows at the cost of losing console and other OS export functionality, but it's also why our future commercial titles will be using another engine.
Construct 3 would be really amazing as a plugin (level editor, object editor, code editor) that can be used by other engines that develop their own exporters/native export with much greater numbers of staff to deal with the nitty-gritty issues.
