I used GM: studio for some time and now searching for new game engine.
Considering few choises and reading pros and cons of those engines.
So about cons that I found on this website
Dependency on 3rd parties for all exports
Since desktop uses NodeWebkit and mobile is Crosswalk, Phonegap or CocoonJS there is no guarantee that your final export performance and quality will be up to scratch for pro level 2d games.
Poor mobile performance
Those comments was written 2 years ago. So did anything changed?
Did there is still performace issues on mobile phones and windows app's?
Thanks for the answers.
