I like it. Ran through the simulator on the mixed setting, and just used the basic shotgun to kill all the enemies that got close. The final boss was a bit cheesy, though - I had most of its armor down, but got too close once and was instantly killed by its multishot thing. Hitting the plates on the back seems to require a custom made weapon designed specifically for that boss, which can break the game for players who thought they could just build whatever weapons they think are fun.
