When users with promising projects begin to dislike the direction of the engine, I think it should be taken into account.
In my years of experience in game companies changes were made to make the community happy, after all, companies wouldn't survive without a user base.
In this case, I was quite optimistic using C2 and quite happy with Scirra work, but their lack of response to my comments made me believe that they simply dont care about their user base.
During GDC Unity announced Unity 2017 and promised features for Artists and Designers which leads me to go into that direction if changes arent made sadly. It represents a lot of work in the current state but business are business.
