So far, so good.
After 5 hour of gameplay ( horde every night ) i can assume it is harder than vanilla, still have cons.
pros:
- icy world, love it ( i didnt expect i will like it )
- more animals ( on first day i found very strange crature, i dont remember name + killed one of "horror" films' animal

, funny music when close )
- hard to find cars, soil and any ore ( i got lucky when i found iron ore on day 1 when i done a mission for trader )
- trader 24h and no defense
- demolisher first day on field (XD!)
- more difficulty than vanilla - you have to "work" to "get"
- lack of wood
- strange snowmans ( from far i think they have some animations, but i cant kill/destroy them when near )
cons:
- i love frozing system of food, but i have time to defrost f**king raw meat - 80 counts defrosted raw meat after 30 minutes (!!)
- too much wild animals, after 4 days i had +200 meat
- too op seats ( from 3 seats got 2 books )
- i think spears are too op - iron spear, lvl 1, can one shot all 125 hp and lower zombies when shot with PPM on body/legs/arms for only 20 stamina ( and yes, i dont like playing on higher difficulty than default, because i hate bulltetsponge zombies, who have to get 50 ammo to kill :') )
Btw, my actual base: ( already got all workbenches, 2 farm plots, +10k iron, all cobblestoned base ( cement mixer is doing 1k concrete ), after doing solid base with traps ( have to get 5 levels ) i will try find some secrets
