3 things to say

Alot better than the first one.
Can you make it in english next time.
Does it ever end?

nice one

Love the music, good choice ;)
I can just shoot forever, the game ends when i get to tired to click on the mouse.
you should make it able to shoot by just holding and make a reload time so that you do not fill the whole screen with shots.
6/10
3/5

Nice sidescroller

I was especially impressed by your attention to detail in the background giving like three separate layers of stars which looks pretty nice. Nice ship designs for both character and enemies, and mouse based control makes it smooth and fun good job man.

hmmm

nice game

Just some tips

A good game but what i noticed was that you could cover the screen with the bullets, meaning that it was very easy. I reckon you could find a tutorial which shows you how to control a charector with friction and acceleration, meaning it would be harder. This could also mean that depening on the difficulty, you could change the speed of the spaceship, making it harder.
But over than that, its a pretty good basic coding for a game, you just need to brush it up abit and run the text through a translator, so english speakers (like me) can read it and play it properly.
