Really love the pixel art here. I also felt like combat was well-done, giving the player enough time to hit and retreat to avoid damage with the right timing. As others have mentioned, the enemies will chase you across the entire map. This might be a realistic representation of Roman centurions, but giving them a max chase distance might have been good, to avoid massive battles. Towards the end, I was just paying the death penalty to sit and slaughter the map's worth of enemies haha.
Great work, this could definitely be expanded into a long form experience and I wouldn't complain :)
