I was thinking that this game could be even better if you added more mod content into the game although I don't have any in particular that I really even know of to mention. I still think that your game would improve if you ask for the creative abilities of more people, specifically mod makers. You could do it on your own, however, you would benefit from asking for help from more people, at least the ideas, like from mod makers. Asking them is similar to asking for suggestions only they already made a mod to add their idea. You don't need to ask for the source code, just the idea (just like asking for suggestions), as for the idea itself, you may not even need to ask, but to avoid problems you should probably ask anyway. You are already planning on adding something into (1.0), I think, that implements an idea from a mod. Really you just need to do that more often, and that's all I am asking. My second request at your disposal (there's no need to listen if you don't want) is that you add to the already 2.5D (or more like (2.25D) graphics. It could make the game very popular to a previously unimpressed community if you could make it at least a little more 3D if not fully that. Although since it is true that people like it the way it is, you could make it a graphics/world spawn option (if people have already suggested this then I am sorry to bother you). You could even make three options (1) The way it is now ( dimensional graphics wise). (2) 2.5 dimensional graphics configuration (with slightly changed world spawn). (3) Full 3D along with world spawn changes (would take longer but still could do a lot of good). Of course this is probably a post (1.0) update but that is fine with me. As always thanks for you consideration!
I'd say it's technically possible, but completely and utterly impractical since it'd probably require building the game all over again. There's no reason they'd do that, especially since they're so close to 1.0.
It's more important to put game content before graphics, especially seeing as it'd require a whole new redone engine. New content that adds more replay value and longevity to the game is a good thing, and I believe the graphics are great as they are.
