I am making this for one of my classes that I am taking for school. It is still in progress, I will add some more enemies and a bomb function. I also will and some bosses. please enjoy and let me know what you think.

I like your game!
maybe add an ammo count because if you just spam bullets it becomes almost impossible to die.

Love it! Maybe the best way to prevent bullet spamming would be to put a time delay between shots, i.e. so you can only shoot once every second or two. That'd definitely up the challenge.
