Thanks for your suggestions!
The game is indeed chaotic, sometimes I find myself overwhelmed while playing it too.
The reason for this kind of gameplay is that it's based on the original "Stick Soldiers" game, which was actually even more chaotic.
I don't really want to change this element of gameplay now, as I believe the game has reached a good and stable point. Making such fundamental changes could "break" a lot of things, and I do not have the required time to ensure this won't happen.
I suggest choosing simpler maps (it helps with the disorientation), teams mode, smaller number of bots, and easier difficulty level.
About the dismemberment, again, it takes after the Stick Soldiers style. Making more realistic dismemberment is unlikely to make the game look better; the chaotic limb-blast is part of the fun element.
Glad to hear you like the head popping, it has been one of my favorite gameplay mechanics since Stick Soldiers 1 :)
