in its current state it is playable, as for the amount of enjoyment well that depends on how much polish you like in your game - the game is pretty good but has some glaring issues,
first thing - no tutorial so had no idea how to do anything, the game has very poor descriptions of what things do or no description at all or if they serve a purpose or are decorations. half the time i found myself making something and wasting resources, unable to scrap it - another issue is carrying something unable to drop it right from my inventory when overencumbered (happens a lot, max carry cap is 64kg which isnt much) you need to find a container and drop the stuff there and come back for it.
secondly the jump, it is alt, weird but it does not even allow you to get out of a spot like the train cars before you place floors, i got stuck in the wheel well and had to throw away 30 mins of playing and exploring the first area and collecting everything. might as well not even have it in the game, you cant jump up on boxes to get away from zombies or use it to hop a fence, the guy legit has a 6inch jump, its barely anything
thirdly the combat is awful, cannot block any incoming attacks, some enemies have cheap attacks that early on you have 0 counter to and if you avoid the zombies and play stealth, the dev has moments forcing you to either fight a horde or fight 3-5 zombies that will 1-2 hit you but take 2- 10 hits to kill. this coupled with REALLY bad leveling, 1 level requires 20-40 zombie kills, and at level 10 its legit 100 zombie kills that is a grind and level 10 youre barely stronger than level 1. additionally, sometimes headshots on normal zombies or even some bigger ones do not count as an instant kill thats gotta change 110%
fourth the areas, they are cool but theyre VERY empty considering you can stop the train anywhere on the tracks, zombies here and there but it consists of mostly empty wilderness, 1-2 small spots either very far walk/run from where the train tracks are (mad annoying) or along the tracks so it is a stopping point for you to venture over to. then there is a main location to explore these are ok to good, zombies everywhere, things to loot and disassemble for loot and materials but some loot is hidden as chairs and barrels because the game doesnt tell you, that it can be disassembled. minor side stories of like a guy getting surprised in the forest and locking himself in the basement because he know he is done for but most exploring is to get stuff early or a few weapons to help make the fight a bit easier. but areas need a bit more density to them, this being more loot to collect means more time spent playing, killing zombies and leveling up, but at the same time not to make it boring where i gotta run 5 miles to find something interesting or cool early
fifth stealth, stealth is hit and miss, because of inconsistent health pools of zombies, if you dont 1 hit (idk why a stealth kill isnt) the zombies can just turn and smack you causing bleeding and making you close to death every encounter. some bigger zombies have a 6th sense and can just see you behind them OR placed in a way that you cannot get around them for a stealth kill even with the bow (which suffers the same damage inconsistentcy)
now for the good
the train customization is REALLY good, there are lots of options to customize the car layout with different walls and doors to really make unique builds or basic ones, i would really want MORE cars to have even more variety in my builds because 2 just isnt enough room even with the double decker concept (which also looks REAL goofy without them being longer like shipping container cars), 4 -6 would be like a sweet spot making it 4 would be like, crafting car, storage car, living quarters car and green house car. being able to have big sliding box car doors and keeping the double decker would be good as well, especially if co - op is added. id also like to see the ability to paint the train and train cars so you can add that extra flair to your home
the fueling idea forcing you to stop and explore is great and i love this however it needs minor tweaking since the engine doesnt coast well at all to save fuel just a little bit and depending on how good you are at the combat can depend on if you are getting ALL the fuel available in a 5 min numerous horde fight or some fuel to avoid the fight and escape
weapons, the variety is minimal, it is an acceptable amount, you are not getting like ghost recon levels of guns and customization BUT the stuff you do get is welcome, the minor changes needed is the smoke after every shot, no modern gun has smoke after a bullet is fired, all guns are smokeless since like 1880, the guns do sway as you move the mouse which is was surprised to see - the minor tweak to that would be ease of use, the handgun is a walther ppk (james bonds gun) which is chambered in .380 or .32, these are VERY much baby rounds (still should 1 shot headshot) but even with 0 gun experience this should be VERY easy to handle for your character
some suggestions:
co-op for sure, my friends and i love 7 days and this would be a great game to play with them too
little scooter or bike to be able to go to these minor locations easier and carry extra loot
more cars and more train customizations
better more in depth combat/ combat that makes sense
better leveling system, progress being 5 zombies, 10 zombies, 20 zombies, 100 zombies makes it super frustrating to level up to be better at the game
