its a nice & cool game - much harder than Minecraft
my suggestion: more importance for Beds / Sleeping, sleep should restore energy and better for health restore too, you will need less calories during sleeping. If you are exhausted you get hypothermia / heat stroke, you need go to bed also, after 24-48 hours you should take a sleep, if not you will get halluzination and later bad consequences. Thirst - (but don't drink saltwater - if we get oceans and salt lakes one day in this game) if you have too much thirst you will get first halluzination and later bad consequences.
If you have low energy and/or you are heavy wounded, you can go only slow / unable to sprint (run) / unable to jump, in a fight you can made only 50% hitpoints - you will die faster!
Drugs, some drugs should made for a short time positive useful effects.
Thatched Roof and Reed Roof
Binocular (but you need crafting this thing, maybe in 2 or 3 stadiums, like weapon, low end zoom 2x, mid zoom 4x, high end zoom 8x e.g.)
Dogs and Horses - as your friend(s), they can also warn you with signs before a catastrophe will hit you (heavy thunderstorm, temporal storm, snow storm, earthquake)
maybe: Earthquake, Volcanos
some things I miss from Minecraft - Villages and dangerous Pillager, maybe Pillager should have own building (robber's hut, half ruine e.g.)
better and more Thunderstorms in summer, I like the "horrific" Thunderstorm / Thunderbolt-Effects, I like the Lightning and Thunder-sounds in Minetest/Mineclone Mod - thats an opensource game - similar to this and minecraft - https://forum.minetest.net/index.php - maybe you can also get inspirations in the Minetest/Exile Mod. Exile is a survival minetest-mod-game too Game Exile: https://forum.minetest.net/viewtopic.php?t=24334, game MineClone: https://forum.minetest.net/viewtopic.php?f=50&t=16407&hilit=Mineclone
Bears (brown bears, grizlys - the most dangerous one and Ice-Bears. They should made more damage as a wolf, but they should be slower and they will stay most of the year as a as loner (only in the mating season, max. 2 bears, male + female). And little bears will grow up only by mother. And bears and wolfs are hating each others, maybe you will see a fight. Wolf will lost mostly if he is a loney-wolf, bears will lost if there is a wolf-Pack. Brwon bears and grizzly will take a wintersleep, they will be only dangerous in winter, if you enter his cave.
Ideas for the Minimap - what about a possibility to draw paths there? And to write for locations a geographic/fantasy-name?
