I tried to organize things a lot, compress a lot of 'function passages' into widgets (a feature I only recently learned of). I should mention though that the last version of IC is a mess in Twine (probably looks like an atrocious spiderweb of carnage) and the one I am dragging my feet on releasing - 1.6 - cuts down a lot of that mess. I'm also willing to make custom logos, favicons and title screens for such projects, to distinguish them and help reduce confusion. I of course encourage anyone to do whatever the hell they want to my game and will put their mods at the top of this thread.
(I refrain from letting on that I am working on a porn game because I don't know what their policy is on such degenerate filth.)
You get answers pretty quickly and they are often quite thorough. I find the best way to get Twine questions answered is on the official Q&A forum or on the Twine reddit.
