There are only two paths.
In the depravity path, no new branches will be added; the routes that open there were always meant to be replaced. For example, the Futa on Futa path was intended to be replaced by Netorare in Week 2.
But I’m now considering wrapping up the depravity path entirely and instead replacing it with shorter “game over” scenarios, so we can shift focus and make real progress on the Netori path.
As for the gallery, it’s something I’ve wanted to implement for a while. The only reason I haven’t made promises about it is that I’m still uncertain when I’ll be able to get to it and if I'll be able to remember how the code works. Perhaps I'm overthinking it but I certainly haven’t neglected this feature.
Have a good one!
