Nice game! It was satisfying to hit the enemies with the asteroid at the start. I did find myself shooting the enemies themselves with the gun once things got more hectic though. Maybe an enemy that can only be killed by asteroids? 
Loved it thanks!

Great lil' arcade game!

Nice, solid arcade action. Playing billiard with asteroids was a fun twist.

Had a good arcade style feel to the gameplay and I also enjoyed reading about the way you spawned enemies too.  Quite a lot of stuff to get working in such a short time limit! I had a good time and you did a great job with your instructions/tutorial at the beginning as well.

It was entertaining to play :) Sometimes I got stuck on the walls, but it didn't bother me too much. The parallax background gave a nice feeling of deep space. The difficulty increased appropriately as the game progressed. Great game overall! It is nice that you had put information about the enemy spawning system on your page.

All I can say is that this is not a boring game, with nice graphics and sounds. I really liked it, if you develop it will be very nice to play it somewhere in the evening, or even better on the phone, the most stable 8/10
