These are single-use powers that include, but are not limited to, a defense boost, an offense boost, completely healing yourself, and using your arm canon (once). The more orbs you collect, the more icons light up. Collect enough orbs and a series of icons on the touch screen light up. Oh, wait, there's also the ability meter. Some enemies shoot bullets at you that you simply can't avoid because you can't duck or block. You just pound on the punch and kick buttons until everything's dead. It's absolutely asinine, and doesn't work in practice. Imagine any other arm-canon hero doing this: Samus Aran, Mega Man, Ash from the Evil Dead series. Astro Boy has an arm canon, but seems to prefer fisticuffs. Every five feet, a little stop hand flashes on-screen and Astro Boy is forced to battle a million robots before the go hand flashes. Most often, these hijinks take place on a side-scrolling battlefield. The robot realizes he's a robot, runs away, and hijinks ensue. A scientist creates a robotic version of his dead son. Astro Boy: The Video Game is an abomination that you should avoid. It tries on all sorts of hats, including traditional platforming, beat-'em-up, horizontal shooter, and Gunstar Heroes-like boss fights, but manages to mangle them all. Astro Boy: The Video Game, adapted from the recent poorly received CG film, can't decide what it wants to be. You may also remember that Treasure made a wonderful Astro Boy game for the Game Boy Advance several years ago that pegged the original anime superhero in a bullet-hell horizontal shoot-'em-up. The little dude's got an arm canon and rocket boots, so he's basically the Blue Bomber with a Rush adaptor. I've always liked to think of Astro Boy as being the proto-Mega Man.
