The Intel chaps have been very engaged and that’s really great...
...but Crosswalk ? access to iOS. Aside from the massive file size, that fact really makes it an interesting but inadequate export alternative to cocoonjs in my book. Just my opinion.
True, it may not have access to iOS. One reasoning due to the fact that Apple still refuses to allow browser engines to run on the device aside from Safari, which doesn't even have WebGL support yet.
Aside from that, Android has the biggest market share in the mobile market. I believe that Apple will someday support web wrappers like Crosswalk. Time is the essence here.
Even if iOS does not support Crosswalk in the future, you still have Android being the most popular.
As well with CocoonJS, very limited, in terms of support given to those that use Construct 2. They still refuse to fix even the most simplest issues, (example- flickering Ludei logo on start up) in my opinion, CocoonJS is falling behind the gutters as we speak, relationships between Ludei and Scirra seem dull.
With Intel and their Crosswalk, they seem to collaborate rather nicely recently, dispite the exported file size, which is still being improved on. You can not just say Crosswalk is "an alternative" to CocoonJS just yet, seeing CocoonJS has been available for much longer than Crosswalk.
My two cents.
