I'd play more of this.
The textures look good both indoor and outdoor, I specially like the grass, including the alternative sound when walking inside it. The view is good, instant movement feels good although I wish I could walk faster.
Thin walls which still take a full tile are unusual, in general thin walls are always between two tiles. In fact it seems you added extra steps in-between the blocks which constitute the dungeon, or at least it's the impression I get, it was not blatant to me when playing that the steps were small but I would 100% cut these half steps anyway.
Thanks for not giving up and sharing.
