There really needs to be some indication of what doors are interactable. Why give the player the option of exploring unfinished areas when there's nothing to do there? You're just confusing the player with dead ends and pointless exploration. This has potential but the dev is shooting too high too early.
And why the hell title your current version as 3.0 when there aren't even finished character plotlines, locales, or whole mechanics? Oh, right, it's all about the grift. Shit is more like version 0.3.
