Pretty dang fun, and a bit of a challenge! :)

I never really thought that video games could be powered by music. That is, until I picked up this crazy-awesome shooter! Fun. Hectic. Addicting. Although, bear in mind that I do NOT recommend this to anyone who is prone to epileptic seizures and/or is sensitive to flashing lights (all for health and safety precautions, of course), because this game has a boatload of those (which can thankfully be toned up to a maximum of 200% intensity, or down to the users preference). And, might I add, these lights add to the action of this game. The more intense your music gets, be it metal, good old R&R, or heavy dubstep (I recommend xKore and Liquid Stranger), the more intense the gameplay becomes, and it may even cause a boss to appear on occasion.
So, all in all, this is a game that I will not likely be removing from my phone (or computer) anytime soon.
