Very nice! I really enjoyed and had fun playing your game.
Even it is a simple idea I felt like having to complete the level. First I was a bit frustrated about the low shoot frequency of my one, then two soldiers. Got killed. But then when I had a lot of following comrades I felt powerful. Cool, how you did this.
The graphic style is fitting. And you gave the soldiers different skin colours, which is good.
Good you included a controller support!!! I am not a keyboard player. With controller it was fun.
