Please try something new with your games.
You've run the top-down forumla completely out of juice. It's been obsolete for quite some time now, and all of your games just revolve around the idea of aliens, zombies, and a very angry playable character who is seemingly just doing this because you know, he can. You lightly reskin all of your submissions, and there is barely anything new with each of them. I give you points though because all the games flow smoothly and the camera work is attractive. But apart from that, you really need to try a new idea with your games.
