Awesome
This game is challenging, fun, and addictive. I enjoy it a lot. However, I ask for two things. The first is the option of unlocking more characters. Just having one character is rather bland. Secondly, I think it needs a story mode with levels and a decent plot. I am dying to know the origin of the mysterious man!!! Add a story mode with levels and multiple backgrounds, and at least one more character and I will be happy.
