Can you give an example as to what those non-generic uses are that Solar2D can’t do?
I understand your frustrations concerning Ads sample project not showing ads, but you’ve received more dedicated and personalised help from @roaminggamer than I think I’ve seen anyone receive, so I find your comment about there being “more supportive options out there” to be a bit unfounded.
Please keep in mind that Solar2D is currently undergoing a big transition and the plugin system and other features are changing a bit. Many people are trying to get their bearings as things fall into their final place.
