Way too hard a game honestly, I beat it and the majority of my time was spent on the last two levels. It's a decent game but the difficulty curve went from jokingly simple to a nearly impossible feat of complex grapple maneuvers, hampered by the wonky physics of it.
I really think the absurd randomness ruins this game, especially concerning survivors and how many and the types of enemies you run into. You can either get an extremely boring and easy one shot game or it is completely impossible to win.
