I've been playing the game and I'm to the 4th "area" which I believe is the halfway point of the game, and I can truly say the level they let you demo at the start is the least interesting in comparison with the rest of the title. That's not to say the game is amazing, but the game does have a certain charm, and gets much cooler as you continue through. The main character continues to pick up more intense and ridiculous weapons as you progress, the difficulty does spike several times, and most interesting of all, a second character becomes playable, whose gameplay style is still cover-based but a lot riskier and satisfying. I'm impressed with the amount of content the game has so far, and while none of it has been ground breaking, it has a certain feel that is quite nice for an eShop game. It's made me consider picking up the multiplayer to see how that fares.
