I ran across appmobi xdk, so here are some of my first impressions from this HTML5 game engine.
Forget about the chrome app, I felt like entering an late 90's span site, popups everywhere, alter messages trying to up sell me on license to something I did not even tried yet. Ater about 10 minutes, I figured out where to actually end the code, but the compared to for example http://c9.io this editor is a joke, though it actually uses the same Ace editor for highlighting, the usability feel weird, does not even expand to full width of the screen, cannot set fonts, and when I hit F5, I get all the promo popups and java alerts again... plus my whole session was lost, have to re-open everything... ok that's enough, let me try to open the project in my native editor.
Looking through the code now, of the demo app called direct box 2d. I see a lot of DOJO style code, classical approach rather than functional, ok we all have our choices, but the code quality is not that great, poor commenting, code would not pass js lint with the "untyped" if statements (funny that js list is actually build in the ace editor as a plugin).
On a good note, I live the concept of the 80's style 2d games, and would love to mess around with some gaming ideas, so I am hoping this project will mature little more, so that it does not turn developers off in the first impression...
