This game is sweet!
Some might ask: Is the game as awesome as the trailer wants us to believe? Yes, every bit of it, BUT it's one of the shortest games I have ever played. To me, it is satisfying enough to maintain a decent replay value. On normal difficulty I would say that you might need an hour to finish the game from the beginning to the end. This game has rather poor animations and colour depth, but a nice retro soundtrack and excellent gameplay. If you need a challenge willing to revisit the game on it's hardest difficulty, then the sweet gameplay is all you need. If you're not the kind of person who enjoys playing the same levels multiple times, then you probably should stay away from it.
There are only seven short levels with a lot of mini bosses and of course an end boss in each level. The bosses are this game's highlights. In fact, you will spend more time fighting them than fighting through the levels. None of the difficulty settings are really hard and you probably will not be frustrated at all when playing the story mode, because of its MANY check/spawn points. On the other hand you will unlock the challenging arcade mode after you completed the game once.
In order to achieve 100% completion you have to beat the arcade mode on the hardest difficulty level, which is one of the most difficult tasks I have ever encountered. The game itself has an extremely stylish gameplay. There are no excuses to hide behind. Just you, the game and a 100% skill. I played it using a gamepad and have to say that there's nothing to complain about the controls. It is responsive, fast and it makes you feel like a blockbuster hero.
