Viability: Playable from beginning to end! All the story events make sense and go well together. There are times where I feel the game is a bit too easy, sort of. Like, I tried just clicking through each option as fast as I could without worrying about what I was actually choosing and it worked well every time. So it kind of feels like choices don't really matter as much as they should? Maybe giving demerits to HP more weight would remedy it. I think it would be cool to know that the seeing the Game Over screen was (more) possible.
Engagement: I think the duration of the game is just about right! Not too long for me to get bored of reading, and not too short for me to think it needs more content. The replayability only helps this idea, too.
Theme: The art and colors and fonts all go well together, very cohesive! It looks amazing.
Presentation: The ticking-down HP was a bit iffy though, because sometimes it's showing and sometimes it's not, so I think I have time to make choices when I actually don't, and I lose HP without knowing I did. So showing that would really help. Otherwise, I really enjoy the application of time with the presentation of text, it helps with the humor in some cases, as well as the intensity in others.
