I was really impressed with this novel!
First and foremost, you delivered on the aesthetics. The sleek pixel art and UI. The retro styled music. They were made with obvious care and attention to detail, and really made the experience that much more immersive.
But I have to give the most praise to the story you've told, and how you built the reset function into the narrative. By initially framing the date as a series of decisions that need to be done 'right', the same way many people playing VNs would see it, you also reveal the dysfunction in that mindset. And the narrtative builds on that! The structure breaks, reality is messy and uncomfortable. But it can still work out!
Beyond the technical detail, the characters feel authentic as well. Having been in the speedrunning/competitive game world myself, I would say you've done a great job capturing both the mindset and attitudes of that space. The petty drama is on point too 😆
All in all, Faultless. Thanks for all the time you put in!
