I can see the point of both sides of this with Ashley's explanations to his hesitation and also what everyone else is saying.
It might be a good idea to try to meet halfway somehow, if possible. So that way Ashley doesn't get swamped spending all his time of the suggestions list rather than actually getting things done in working on C3. It is kind of frustrating that there are things like tiled backgrounds can't be animated at this time, and you'd think it'd be a given that jump throughs also have collision tags like solids, but I also understand Ashley is probably spreading himself too thin with all that he's doing currently.
It's times like this I would look to hiring more people if possible, but I can't even pretend to know Scirra's financial situation or the laws of the country they're based which are likely totally different from the ones in mine.
