-= Exposure =-
Exposure would bring a whole new aspect to the way this game is played. The only requirements from you guys as the developers would be to implement an actual character into the game instead of floating arms.
First off, there would be a bar in the bottom right corner showing your exposure to the wide open. The exposure is affected due to the day/night cycles and how much clothing you have equipped. For instance, if it's night and you don't have any clothes equipped, you would be losing exposure at an alarming rate compared to if it's day and you have a heavy fur coat on. It's kind of like a temperature thing, but exposure sounds nicer. If the bar reaches halfway, you go 50% (editable) slower and if it reaches the full bar, you die.
As mentioned above, you would be able to craft clothing and there would be day/night cycles. First off is the clothing. There would be a new tab in the crafting menu and it would have lower clothing tiers (such as thin shirts) to higher clothing tiers (such as fur coats). You may be asking "how would you go about getting fur for the coats or cloth for the shirts?" Well I'm glad you asked! The thatch will be used for the cloth and the cloth makes every clothing item there is while there are little furry animals in the water such as otters and you would hook them in and stab them with spears.
So overall this addition would be easy to use and have a very high impact on he gameplay and make the game much harder! Thanks for reading this submission and have a great day
