It is raaaaad.
More on this later!
Actually, I was kinda disappointed. First, the demo is way too short. You don't even get a boss fight out of it.
Second, the controls are really limiting. This may have been great in the original game, but today, I want to fucking jump. I also want to swing from a straight up position, and grapple forward when I'm in the air. Also, I want to FUCKING JUMP! It feels like you are really just trying to make up for the fact that you can't jump just to get around.
The music and graphics are good. (I like the throwback to the old skool music remix.) The dialogue is pretty funny. The hacking looks stupid. And god fucking dammit, when I point my stick in the diagonal stick, I want to fucking grapple diagonally! It's easier on the digital pad, but I've gotten so use to the analog stick.
Overall, it's a great remake of the original game, but not a great game in general. It would have faired better in the 80's, when you couldn't go to the left of the screen in Super Mario Bros. (It seems like this is the new Capcom, where they dumb down games and call it retro for profit's sake.)
