Yoo this game has some serious potential, and I mean as a legit game. and yes, this is a long post, it's basically my thoughts on the game after about 5-6 hours of playtime
(version 0.1.2.0.5) Honestly, the world/map is fascinating and fun to explore with a decent amount of story-telling in just the environments (though navigating the terrain can be a little difficult at times), it also has some interesting story elements that's got me curious as to how they'll be explored as the game gets developped, decent enough stealth but still a little bare-bones, gun/bow play is fun and satisfying (also, when you first get a bow, your character will suck at it in terms of getting tired fast and not being able to shoot far or that accurately and have to get better by shooting more), a satisfying enough level system, melee with fists is super satisfying, animations look great and fluid, and yeah it's pretty buggy, it has crashed quite a few times (usually when saving the game, maybe 1/3 times), and it's not super well optimized, running an RTX 2070 and had to set graphics to medium to get it to run smoothly but it still looks great on medium.
The health system is pretty neat, you can break bones, get cuts, get food poisoning, insomnia, depression, stress, suicidal, manic, psychotic (hallucinate), bitten by venomous snakes, stung by scorpions, etc etc and they all have their own remedies. What I find cool for trying to cure depression, stress, etc is that you can either drink booze (though drinking too much just makes it worse), listen to music, smoke cigarettes, and read a book or magazine, pretty cool! Also, your character can be quite clumsy, God forbid you sprint over a fallen branch or crack on the road cause your character will trip and go flying rag-doll style (not gonna lie, pretty satisfying though).
The enemies are interesting and both fun and hard to kill, especially if you're not prepared.
The crafting system is decent enough allowing you to create clothes, weapons, tools, meds, etc. but if you want better gear you gotta go looting/killing.
Building is pretty bare-bones at the moment but it seems like it's going to be pretty in-depth, also, it's very much akin to the building in "the Forest".
Storage system is very "DayZ"-esque with clothes, backpacks and taking weight into account. Also the way clothes get visibly damaged is pretty cool.
The sound design is great!
It has a perma-death mechanic after 3 deaths but you can disable it with cheats. And getting to the cheats, they're super fun to mess around with, with one of them giving you wings to fly! (Rab-Bit, or you know what, Sir Evgeniy Ekimov, please, please keep the cheats as a feature even when the game actually releases, PLEASE, they're REALLY fun)
Like seriously, there's a lot here and for only being in version 0.1.2.05 and for being made by ONE guy, that's mad impressive, I can't wait to see what's next and I really hope Rab-Bit keeps working on this game, it's great!
