I was surprised by this game because I wasn't expecting a full-blown RPG. The Lovecraftian atmosphere is well-rendered thanks to the dark setting and the intense battle music.
While there is a clear setting the player is moving through, the immersion is broken when I come across scenes that could have been better represented graphically. For example, when you reach the river bank, you can see the river and the stone floor you are walking on. I would like to see this scene better represented. Also, in the scene where you come across a mural dotted with symbols, it would be nice to have a graphic representation of it, which does not have to be detailed. Even scenes where the scene is described only through text could very well have an image to help the immersion.
I will refrain from commenting on the game mechanics, as they are beyond my current experience. However, I noticed that there are really a lot of fights with hostile entities, but no interactions with characters of different types. Including a mechanic like that could give the game a sense of greater spaciousness and expand the game lore. Unless I haven't played enough to encounter these types of characters that are actually already present in the game. In that case, I take it all back.
It is definitely a game that needs to be played to the end to give a definitive final judgment and more experience than I have.
