Some one once said 'Simplicity is the hallmark of genius' if nothing else this game IS simple, but I didn't say EASY the difficulty ramps up the further you get into the leverls. It's a shooter in the same manner that Space Invaders is... There are 99 levels and of those there are three basic goals of each level; and also three different modes The Three goals?: 1) Kill All enemiers 2) Survive a certain amount of time, 3) Kill a boss, there may be more goals but it's still early and that's all I see. There;s nothing wrong with that though.... Some of the best games ever like Space Invaders was built on this same simplicity with ramping up challenge difficulty... You can replay any level once it's unlocked but early on there's no real reason for that except if you want someone else to try it,,, There is patrol mode where you clear out a level, Survuval mode where you try and last as long as possible with the monsters spawning at an increasing rate and they become increasingly popwerful, aqnd harder to kill. There are various power up which affect how the weapons fire and so forth t increase the depth of the game by small increments. Don't expect a lot here, it would have been better at a bit less but I have no regrets, the technology works 'FLAW-LESSLY' pardon the PUN. It is fun and in the same manner as Nintendos Wii Fit, this single game can get you up and moving around like exercise in moments without even realizing it. Since the story line is small and direct I gave it a low score for story, the music is nothing special the interface and responsive-ness works great though. Although separately I gave it varying levels of scores, this game will certainly entertain and I'm fully convinced this is the fore father of a whole series of game styles which it will spawn As they say, the sum of it's parts are greater than the whole. You might just as well get it while you can, there certainly is NOTHING else out ther e like it that's for certain and it IS entertaining.
