This is fun! I liked the gameplay loop. Some clearer information to start out would be helpful - I didn't know how to sell anything until I found a town portal scroll, so I was just trashing gear. Maybe start the player in town so they can see the options before entering the dungeon? It would also be nice to be able to just drag the cursor over the gold to pick it up, or click and drag if you still want some friction.
Some proofreading would help! There are some typos here and there in the items and stats ("Strenght", "Helmer", etc)
