The Flash, now with fresh Game Boy scent
The Flash game for Game Boy Advance is definitely one of the greatest action games for the Game boy. The game has you play as the Flash, in a beat-em-up that reminds one of Double Dragon. Besides punching, you can pinball attack to enemies, where you zoom back and forth between them hitting them, a whirlwind attack, where you run around an enemy striking them, and a ground slam attack. The Flash can also jump into "Flash time", which slows down the enemies, so you can get some extra hits, or get out of danger.
Villain-wise, you fight some classics: Grodd and Zoom, along with Circe, Killer Frost, and Braniac. Additionally, on your last life, if you die, as you stagger, go into Flash Time, and you can fight the Black Flash. It's pure awesome.
Bonus wise, you can race Superman, which is a pretty neat tribute to the comic book races between the two.
Buy this game. It's awesome. The Flash demands it!
