What a wonderful game. I like absolutely everything about it. Aesthetically, I'm in love because sometimes a simple, well-crafted design in ASCII and standard colors can look better than a graphic tileset.
In terms of gameplay, I found it interesting and was surprised by the amount of movement and attack patterns you've been able to implement in such a short amount of time. It feels fluid and rewarding when you can dodge your opponent and then position yourself to end their life with a combo.
In short, a fighting game taken to the category of turn-based roguelike that has managed to capture the essence of the genre in an elegant and fun way. I tip my hat to your well-executed idea. Congratulations.
