This game is fun, and for your first game ever it is simply great. The idea is pretty smart, the connections between loop and shooting asteroids is interesting lol. Artwork and audio are pretty good. Narrative isn't there which could have been interesting (why are we shooting asteroid belts) but it's all good.
Other comments have mentioned the things I wanted changed like better tutorial and old crusty dying ruining the game. One that I didn't see mentioned is maybe having more control over the laser, so less bursts that deal more damage. That could just be me however. On the other hand a mechanic I really liked was strafing, it's hard to see that in games and it just makes movement so much smoother so hats off to you. Congratulations on making an awesome first game!
