The stickmen are usually the heroes in their games, but sometimes their just the other beings in the world. This game has the stickmen acting as the targets and it's never confirmed whether you're also a stickman. This isn't important since what is important is that you can't just throw grenades around all over the place. Collateral damage is a very real thing to think about and you never know whether someone will accidentally wander into the blast zone. Your grenades have also been tailored to be more controlled, so you need to think about how to get the most out of each blast.
