I loved this game when I was little. I'd always do Airman first then Quickman since Airman's weapon would kill him in two hits. After that it was always Metalman, the game was cake after that. But I'd always do Crashman before Flashman since his bomb killed him in two hits. The metal blade also killed Woodman and Bubbleman in one hit. Woodman and his level were very easy if you had the Metal blade weapon, almost everything died in one hit.
