Space Hunter 10

You should be familiar with this game. It has long been not new, but interesting. At first glance, it's pretty simple, but at second glance you realize what it is. You control space ships, with the keys W, A, S, D, and using the space you shoot at enemy space ships. At first, everything is easy, but after a while, these ships start shooting at you, so watch out. Good luck in the game!
