As a practicalist, I think there should be full access to the code as all the other editors out there have full access and although none of them in my humble opinion compare to ORK, that is a feature some of them use to advertise to generate sales. If there's no practical reason to reserve any code, I think it should be available.
As long as I can get the stellar help I've gotten, that doesn't really matter to me. But as mentioned, the editors out there use code accessibility as a selling point and maybe it is a good selling point.
I leave it up to you, gil. I do feel more comfortable having full code access in ORK1 because I can check things and try to understand things but basically I just want things to work and I don't care how I get there as long as I can get there.
Using the old 2d editor I was using, I had no access to the code, but have had over five years of productive game-making with that editor that generated sales and happy customers and they still want more. So all I care about is that things work, my players are happy and I get some income to invest in new graphics. : )
