Hey!
I'm actually quite impressed by your work so far, at least by your main focus for now, those 3d models.
But I've been thinking, even though it looks good and has certainly its style, there's nothing that really makes the world of Ferrum stand out, everything is..."too generic", not interesting to look at, even though the models themselves are really good.
Do you plan to have some sort of lore (basically background information about the world) scattered around the various maps? Even if you are not interested in implementing a main narrative in your game, I think optional information is always a good plus
Maybe some notes will be able to make you aware of the location of a secret chest hidden by another survivor? a sort of secret unmarked quest, if you will. Others will tell you about certain rituals? What about pure "side-stories" notes?
The potential is there but players need an incentive to keep exploring, a reason to choose your game over someone else's, I think those little tweaks can be a good starting point to begin to acquire the right mindset to keep working on your game.
I'd love to continue this conversation on Discord If it's not a bother.
Keep up your work anyway ^^
