The Power (2008)

The Power is a nice metroid-like platformer that sports juvenile writing and a rather dumb plot, but well done gameplay in a neat retro style. Like in Metroid you advance by collecting health and rocket upgrades that increase the number of each you can hold, as well as main upgrades that enhance your abilities, like destroying certain kinds of walls or the ability to move easily under water.

Before you get the main upgrades you have to defeat one of the well designed bosses. Each of them can only be defeated with a special tactic. Overall, rather short and easy, but still very entertaining.
