nice art style. I meet few bug like the popup dialogue cannot be turned off. I was hoping to see the control panel sooner, it took me a while to figure it out. A little more personal opinion: I think most PC players will use W,A,S,D to move instead of arrow keys.
Don't forget to check out the prototype of my upcoming roguelike dungeon crawler. Although it's just a prototype, it already has a lot of content. I really need feedbacks to improve my game.
