Good Idea to put all wishes and suggestions in one place
I got some thoughts and maybe they are worth implementing:
a Smoothie for Night-vision and one for enemy highlighting in a certain distance
Weed-seeds would be nice for cooking, crafting, growing some on your own and of course animal food
the possibility to stack the storage for weed stems and plates
decaying of not used plant parts which are not in a proper storage
a (expensive) mutation to draw more than one arrow with one shot
I will add more as soon as the ideas find me
Edit:
I discovered that stamina decreases while being on a rope without going faster. It would be nice if sprinting would work while sliding (and as far as I know it would be the only game where this is possible ) BTW in FPV the X-axis is locked on ropes like it is on ladders.
Note for the Devs:
Usually camera is locked on 3rd person while on rope but after opening inventory it is possible to switch it. This info could help you I think ^^
