First of all: I love it when people take the risk to create a 3D game in a game jam! And I think the setting is just perfect for what you tried! The room looks nice and it's cool to interact with the different objects in the rocket. I just think that the placement of the chair is not that great as it's blocking your way to get to the fire button and the controls. And when you try to jump you can get stuck a bit.
The gameplay loop works well for me :) Managing the different errors can be stressful (as intended) but rewarding. But the button to shoot the asteroid could've been more obvious. I guess you had not enough time to create a real model but changing the color to red would have helped already. I completely missed it the first 3 rounds.
And I have to add that I love your credit page. It's really cute!
Great job!
