Hey, great looking characters. My first play I just started running around looking for weapons. Being silly, I just started going up and to the right. Nobody told me I should protect something. And for like 2 minutes nothing happened. I thought that the project was unfinished. And than BAM - Game Over, something was destroyed. Then I read your description, and tried again. Well, I have to say awesome work. But to explain your controls and guide the player a bit. You as a developer know the goal of the game, be me as a first time player didn't. If you decide to continue development, do take that into account. Keep up the good work!
