The trick I used for the Hard Badge was moving clockwise starting from the center enemy. I threw the gun to stun the first enemy on the left, punched him twice, and - from that point on - used two guns to keep the next enemy stunned long enough to reach them.
9.3/10: This was a great game to play. It was a shame that during the last boss I was unable to use Goose ex Machina to revive myself. It was annoying to constantly almost beat the boss just to die to a meteor or my health running out.
