Needs work
Well, what I'm seeing here needs a lot of work...
I'm assuming the spaceship graphic is a stock picture that comes with the games factory because I've seen it in other submissions. I'd first suggest getting a different ship - something more personalized.
The background is a brick wall, which is a bit strange. Not only that, but the meteorites look like almonds to me. I would recommend changing both of those - unless that's the look you were going for? It just feels like I'm shooting almonds with a spaceship in an alleyway at this point.
The sound effects aren't terrible, but the firing sound is a bit strange...any way to turn down the volume on it a bit? I, personally, wouldn't mind if you had far more asteroids/almonds spawning and an autofire option, personally, but I suppose it depends on what kind of a feel you're going for.
The score counter? at the bottom right doesn't work, it just spams random numbers which looks really strange and gives a broken feel to the game. I would recommend either fixing that or scrapping it altogether.
I think the biggest problem in this game is that is has no sense of purpose. We aren't competing for a high score because the high score doesn't work - and correct me if I'm wrong but this is only a single level. If you added more levels, some bosses or different ships to fight, gas canisters to collect, just about anything it would feel a lot more full and complete to me.
Keep at it, and don't get discouraged by low scoring reviews. Just take the criticism to heart, and learn something from it. Don't take it personally at all. Hope this helps.
