Good job completing a gam jame.
Since you have a kickstarter and youtube, I'll assume you're looking for critical feedback.
I liked the buildings. I liked the upgrade page. I liked the bedroom scene (the first time through).
It wasn't clear to me what my job was. Game page said go make friends. In-game GUI said "buildings left". When I tried interacting with the buildings, nothing happened. I saw some particle effect, but it wasn't obvious that had any impact. (Later on I figured out that I was supposed to destroy the buildings. I guess I'm killing them so they won't die in the supernova?)
The gun didn't always fire a bullet. Not sure why: Reload timer, colliding with player avatar, some other issue?
The intro scene was cool, but if you have no in-game help or pause, then it's a cardinal sin to have unskippable intro scenes. Players will have to quit your game to go read the help text, but they might not come back. I sat through the warning info and bedroom scene 3 times. Why?
Needs much better audio.
Check out any of the GDC videos about game-feel or juice or "The art of screenshake". Every action the player takes should have immediate and obvious feedback. When I upgraded skills, I didn't feel any different.
It's clear you know how to use Unity and make games, so it's time to start working on game-design and juice and polish.
I should also say, if you keep working the way you are, you'll be an unstoppable force in the game industry within a few years. I love the amount of content on your youtube channel. Keep it up!
