It's the most innovative shooter I've played in years!
This game has very few mechanics, but they are polished to perfection. It's incredibly satisfying to play! The main story is very short: you can probably finish it in an evening. However I'm actually enjoying playing through the challenge modes, which is a first for me.
You might not get that many hours out of it, but you will have a lot of fun.
The gameplay is incredibly good, and it stays good throughout the whole game. As of writing this, I haven't tried any of the unlockable levels, but I believe I would have happily played through a campaign at least one-third longer without becoming tired.
You've got different ways of tackling a level, all of which are satisfying. You'll feel cool no matter what you do. When you mess up, it's usually your fault, not the game's, and you'll have an idea of what to do differently.
The "feel" of the game is great. Foe after foe will reel, shatter, tinkle on the ground. Grabbing guns out of midair, throwing things at people. Awesome!
The levels go by fast, and oftentimes you never know how many more enemies will spawn in. When they're done, you're pushed immediately into the replay, which made me a little sad that I don't get to poke around the environment. But maybe it just works better that way - whenever I had time to wander around, there wasn't much more to see.
The [MINI-SPOILER]body-swapping mechanic introduced partway through the game didn't add much for me, and I often forgot I had the ability because the basic toolset was more than enough for most situations. I wish there's been more katana focus instead.
My big complaint is the story, such as it is: It interrupts far too often, and doesn't seem to fit the surreal-yet-badass theme of the game.
Every five or so (?) levels, you have to go through an unskippable interlude. The interludes take away control, and make everything you do in-game feel less badass, less surreal, and more like pointless schoolwork (that just happens to be fun). Which makes the short length of the game even more frustrating: you never get that badass feeling back.
The story doesn't resolve, become more substantial, or even go anywhere at all. It just hangs over your head and makes you feel crummy.
I hope this was a coherent review!
If you're on the fence, I'd say to buy it on sale - doesn't need to be a big sale, just any little sale.
Full screen flashing and distortions, forced and unskippable. Unskippable "story" sections composed of banality and graphomania. The core gameplay is good (sans the randomness of shotguns), but the game tries too much to prevent me from playing itself.
