Here is my first submission.(May be more)
The speed is now about perfect IMHO.
My only complaint, and this wouldn’t be the first Asteroids clone I have had this complaint with - the roids can appear right over top of you and kill you instantly.
Other then that - it’s like a flash back to the early 80’s 
Great work!
I liked that feeling of realistic movement! And asteroids being crushed into smaller ones. Nice game.
A classic! Well done 
I love this! It’s like a perfect reproduction of the original Asteroids! Great work!
Now see if you can fit the bleeps and bloops of the original. 
Perfect clone of asteroids - you even have the UFOs
