That sounds really promising. When I started working with C2 for mobile apps there was even no e-book describing step by step how to build a mobile app with C2 and IntelXDK and I struggled a lot. And it was really painfull process to learn everything so I was really not in a mood to start this struggle again with CooconJS, Coocon IO or anything else.
BUT... Intel XDK is not perfect as we all know. Performance is pretty poor, and with every new Crosswalk version release it was worse and worse. And on top of that there are mobiles which simply cannot hadle it at all. It is a minority but still.
So this was really discouraging to build more mobile apps with C2, and I think many peaople simply left C2 because of that.
And I'll say one more thing. I've never shared that on the forum, but I think it's a right time. I've built a mobile game with C2 (pretty simple trivia game). First it got its release on Polish market (Polish version). Simply to do good testing on smaller market before releasing WorldWide in english. You can take a look on it here: https://play.google.com/store/apps/deta ... polskiquiz
As you can see it has pretty decent graphics, and we had VERY good feedback from people we were showing the game (I'm saying "we" cause I've released that with a group of friends). But still it has a mark of 3.9 now... which is not the best score you would expect. Once we put the game on Google Play the nightmare started. Many people had performance issues, game was blinking, wasn't working at all etc. We had to ban several devices at all (including Galaxy Tab 3 series!) and rise android requirement to 4.4 KitKat to be sure game is runnung on some decent/modern device. Till we made those changes we recieved a lot of negative comments and bad marks. Not because the game was bad, but because it wasn't working. It was really a pain, especially when you invest some money in marketing.
Anyway I was waiting with releasing english version till C2 will get some better "partner" to compile mobile games. And it looks like the time has come!
So again. Cocon IO sounds really promising. Thank you part12studios for sharing!
