Good concept.
Such concepts are great: side scrolling, shooting, physics. What else can you want? It should be perfect.
Unfortunately this game fails. The biggest flaw is the lack of sounds and music. The world in game is EMPTY, there are no basic sounds in it: walking, jumping, hitting, screaming, only unvaried weapon shots. Also you say that this is like MS but with ragdolls. Metal slug is a very intense game with enemies everywhere, this game is pretty slow. Ragdolls are here, well implemented but they also fail! Why are the bodies flying 25 meters away from a single shot? It spoils all the pleasure of ragdoll effect. The graphics and animations are pretty good, cant say a bad word about it.
This game had some good potential you wasted on not polishing it enough. People should consider this game rather as a demo and it belongs to NG alphas. I'd love to play this game but as a finished product.
