I think this game has great potential! I love the art style and the old school gameplay. It is very accessible, reminds me a lot of the RPGs I used to play as a teenager.
The dungeon music is also very relaxing! Not sure if that is intentional though haha
I would consider changing the sword swing to left-click by default, it just felt a bit unusual with right-click. Perhaps also auto pickup of basic items like gold.
Look forward to seeing more!
