I'm enjoying this game. I want to emphasis, though, that this game is not a third-person shooter as we've come to expect them this generation. The music is great, and I enjoy the humor. Certainly not a triple-a title, but I am having a lot of fun with it.
So far, it's really easy for you to lose your limbs which can be frustrating sometimes in combat, since you have to essentially focus on picking up your limbs to continue fighting. You can still fire your guns, for example, if your arm gets cut off, but I don't know how good of a solution this is, since I'm not sure if your arm auto-targets enemies or not. I wouldn't call the mechanics broken as this is their mechanical tradeoff for dying, so to speak. As expected, the actual look of you rolling around with your arm(s) attached to your head is pretty hilarious and goofy. It looks like there are some minor puzzles involved with the dismemberment, though nowhere near on the level of a, let's say, Duke Nukem Forever. I only wish Bryce wouldn't talk so much when he loses his limbs. I have a feeling I might hear the same lines a dozen times over before I'm done with the game.
The game also gives you an upgrade mechanic which seems like it will be useful in the future, such as more gun damage, higher jumping height (which I can already see the uses for).
So far, the game is great, goofy fun. Reminds me a lot of character action games with guns from the PlayStation 2 generation, which is a good thing. Nothing overly ambitious, but it does what it does well enough. I'd say this a solid three stars, in my opinion.
