Really cool dungeon crawler concept that has some beautiful pixel artwork. The biggest improvements I can think of would be allowing for directional movement to be repeated if the arrow key is held down (it got pretty tiring just pressing the same direction repeatedly when I had a straight path) and adding some respites or another type of pace-breaker. Nonstop puzzle-oriented combat can feel somewhat exhausting without something more noticeably relaxed to slow down with. Otherwise, great work!
