Hey! It pretty fun game!
It's hard I couldn't stand 60 seconds but still I tried many times. I like the game peace, there is no delay between death and next try.
I like your design, hitting enemy prevents bouncing so you are rewarding for good aim but still we have enemies that we can only kill by bouncing (front shield), that's really creative idea.
I agree with others that auto-fire feature is not really necessary, I got the idea but game is pretty hard without it.
Music is good, well match for the game.
I think this game could be divided into different levels where you scale up difficulty so player could have much more fun with completing them and you will have possibility to implement progression into the game (shields, dash, extra life etc).
Congratulations on your submission! Keep working!
