I loved the first game, and it is unfortunate to see what they are doing with the second part. It is not fun, it is not fair, and it is not balanced. Many mechanics/strategems do not work from a 3D perspective as they do from a top-down perspective.
It would be fun even with all this if your character was not an f* stick who eternally happened to be in ragdoll.
Fix your game, please. I want to love this one. I really do.
