About 20 hours into Drova and I have some negative things to say.
Not having a minimap, highlights or fast movement makes this game an utter chore to play. I can relate to the idea of not guiding the player too much, but when every other quest is "talk to X, then to Y, then to Z", and I have no idea who and where this people are, it practically means I have to go through the whole town every time. The "not guiding" part only works if there's not a specific order you need to do things in.
The lack of a minimap also comes into play in exploration, because the game uses elevation levels to block movement. Quite often I can see where I want to go, but I have to spend a while finding the right path there, because for no obvious reason you can just walk right up to it.
Lack of fast movement comes into play because there's lots of occasion where you need to travel through places you've already been to, and hence where there's nothing interesting going on anymore. The game isn't that big though, so it's just barely below my annoyance threshold.
Out of the 20 hours, I'd say about 5 is running through town searching for NPCs, running through already cleared maps, and pathfinding because everything needs to be a maze.
The game does some neat things though, like the map, or the investigation mode, and the combat is pretty nicely designed, although I'm utterly hopeless at it.
