I guess I am alone in this, but I really don't like this game.  Granted, I've only played the first 3 levels, but I just find it frustrating and irritating.  I do really like the games style and graphics (though the 2D art is crap), but there's a lack of finesse to the controls (again, because of the physics model)  that leads to a lot of cheap deaths.   The thief's grappling hook is probably the worst offender; it shoots through things, disconnects while I am swinging over spike pits and aiming it is awkward (on keyboard and mouse anyway).   Maybe it gets better when I level up more and learn new abilities, but as of right now I am not compelled to play any further.
