Oooo, I love your third point. I was also hoping that environmental hazards and traps like the ones you described could be added in the future. Especially plants, bondage/chastity like cursed equipment or aphrodisiacs to name a few things I was thinking about. In a post from a while ago someone also suggested something like ghost hands. Some of these things (such as aphrodisiacs) could also be combined with status effects and finding ways to cure you.
But I think that it's still a while off, if something like that would ever be implemented, and these comments get a bit flooded with suggestions, while I think that Raliv still has a good amount of things they want to implement first.
