This is fantastic, love the new enemy designs and their victory celebrations.
But the game is moving away from what makes it unique.
I first started worrying about the original release when guns were introduced a few levels in, and the game is now further away from the awesome angry footing.
My concerns were kicked into the corner and exploded by the appearance of the kickable exploding barrels, but their placement makes them impossible to kick in most cases and occasionally blow up when you try.
The shotgun is well made, but enemies with shotguns are even harder to engage in melee.
The player being worse with guns, more kickable objects-turned-projectiles and a distance-closing kick would make me very happy. We have enough regular FPSs.
