Xray, thanks for your suggestions! It's not the final version of shooter and I'm going to improve it. The main problem is that it is very difficult for me to make any good design. But I'll try to add here something entertaining, I have some ideas about that.
Xray, Alian_RG asked to help him in one social network with simulating waves. So I made my own scene to show another way to make this. In the scene I made EVERYTHING myself, except one polygon with thruster. Maybe this scene uses his concept of using rectangles, but everything else differs.
Anyway, thank you for your comment, I'll add a credit
