Interesting idea, but I'm really bad at it! I played about 4-5 times, and the ship is just so good at escaping. I never got close to it at all. So I tried pumping out more asteroids, hoping to make a collision with the ship before another asteroid, but the odds of that are not in the player's favour. I also tried firing them directly at the front of the ship, but it was always able to shoot the asteroids before they got close. I tried firing lots of them in the same direction too, to minimise the chances of them colliding with each other.
I might have missed an essential feature, but I couldn't see any way to make the asteroids faster, and couldn't see what affected their size. If these are related to the length of the line or the amount of time you wind up for, that wasn't communicated to me. Without feeling like I had agency I lost interest pretty quickly.
The presentation is lovely. The sounds are functional. The story is pretty fun too. But for me, the gameplay wasn't quite up to scratch I'm afraid.
Still, great job for 48 hours!
