This is rather short game and this is how the level looks like: There's one stickman standing on the hill next to a cannon, while three enemy stickman soldiers are disembarking from the sea shore.

As you can see in the video below, your job is to make sure all 4 of them die, one by one. As instructed, it is a must not to let one stickman see the other one dies, meaning that you can't just drop grenade on top of them. Three enemy soldiers will climb on top of each other making human ladders in order to reach the guy on the hill. One stickman gets to the top, one stays down on the shore while the third one tries to sneak in through the tunnel.
