I made my own version of Space Blaster.
But I have a problem when I tried to shoot lasers to enemies. That lasers just like move trough the enemies. but when I get hit with their bullet, I take some damages. When the spaceship is on collison with a enemy, it also take some damages.
whereas all of them are in the same layer, and I think I did exactly like the examples.
What is my mistake at this point?
