Publish games to mobile platform like iOS , Android & Windows is still a big pain because not many essential features listed below are not supported which really makes your game inferior to other and doesn't have a chance to hit or even to set a level field in very crowded competitive market.
Features like ,
Social integration support (facebook, twitter) - make ur game go viral and drive organic traffic
GameCenter / Open Feint leaderboard/achievements - This has become very vital for gamers to keep playing ur game.
In-app purchases - the only hope u can make money out of games in a non-invasive way nowadays except Ads which is very invasive.
Currently there is only one platform, CocoonJS which i can trust some how to get the games ported. Even though they provide lot of the above features ,
Scirra hasn't implemented much of them in the CocoonJS plugin, while the CocoonJS platform has exposed most based on their demo programs,
Even some of them implemented doesn't seem to work nor there is no documentation for how to setup or make it work like the in-app purchases and any question asked about it doesn't seem to get a proper reply or mostly ignored.
I feel Scirra's focus is expanding to other platforms in recent releases rather than focusing on a single popular platform like mobile and provide it with a complete set of minimum features for the platform to be competitive compared to other platforms.
I hope they understand the need and address the concerns and hoping others also have the same feeling and can vouch for it.
I know few people develop games as an hobby and i also believe that there are others who like to make some money as part of their hobby given amount of quality time they spent on developing the games.
