This game is a strange but interesting mix of a fighting game and a "Bullet Hell" Shoot'em Up, and at first it's really confusing. But after a few minutes everything starts to make sense and it get really enjoyable. The game system is quite simple: A for boosts, X for simple attacks, Y for special attack (guided projectiles, or temporary power ups for the simple attack), B for the secondary attack (bullet hell, mines...), right trigger for the shield and the lest trigger for the mega attack. It doesn't take more than a minute to get used to the controls, as expected from an arcade game. This is a really enjoyable but of course quite limited in scope title, old school gamers should love it.
