Ok. First, i need more time, than i expected. I need more practice and much more sprites. I have some basic weapons and enemies, but i still have to do backgrounds and efects.
Now some more informations:
There are going to be more kinds of enemies. One of them is Heavy infantry.
This units are heavily armored in strong armor, which is impossible to penetrate with normal gunpowder wepons (even 50. cal. rifles cant penetrate). This units are armed with laser rifles or riot shields. They are extremely dangerous!
PS.: Sprote is still unfinished, but there is not much to do. I will just add more armor.
