I had fun, and it's impressive for a game jam. I know how time consuming writing can be, and figuring out how to make a game as well isn't easy. The art was nice, even for MMD, and it's always fun to see passion in a project.
Have a bit more confidence in your work. The writing was fun, I'd say you successfully dodged the self-insert wish-fulfillment with the debate about saving her, and I'd certainly play more of this to see how you'd handle the others.
I do recommend looking for a team next time, or if you continue this. The Holojam Discord is full of great people who are really welcoming and encouraging, I'm sure you could find a team there. (Note: This is me being a hypocrite, I sent one post looking for a team late, and immediately gave up and just made my own game because that sounded easier than talking to people.)
