The Fleeing Entity

In this trippy top down shooter, you control a human looking entity to shoot every single person. Every time an enemie is killed, it drops a powerup that will improve your weapon. Story : "So yeah this "high on drug man" managed to escape that "experimental laboratory". But the funny thing is that it seems to go to a precise place with a precise objective... which one ? I dont know but thats probably not a good thing for everyone..."
