Viability: The game plays very well. It is very straight forward with its decision making, and I appreciate the lack of black and white answers. Even if things seem like they'll go south, you keep the reader engaged with the lack of hard-set choices.
Presentation: The format of your text is great. It's easy to follow and although there is a lack of some visuals, the way you have altered text is great. I love how certain words are customized depending on what they are (for example, the text "glow" literally glows). I think its a nice touch to feeling engaged within your narrative. However, more visuals would really accentuate the thematic of your game. The story is very clearly one of tension and fighting, so some interesting visuals could be at play, whether they are metaphorical or glimpses of the fight that we get to witness.
Theme: The theme is clear. The decision making fits well with the battle at hand. It would be interesting to have a timed mechanic attached to your theme. Battles require you to have sharp thinking, so implementing a timer would be a great way to accelerate your game.
Engagement: The narrative really pulls the entire game together. Its description and obvious knowledge of fight scenes really puts the audience in a chokehold. Your strength is narrative- keep pushing it. You have a very solid flow within your story. I would've loved to see more mechanic wise, even if it was as simple as implementing a timer. Obviously some visual approaches would be great too, even if they are simple or just "sprites" that we can see pop up on screen. Sound effects like the whooshing of a sword when popping into a passage would be amazing and very gratifying!
Overall, I'm excited to see where this goes! Your narrative is already fantastic. There is clearly a lot of passion in this project.
