Minor oddity: You can get the final medal without getting "LIKE", "THE MOVEMENT" or "ALL OUTTA ASS". It's pretty fun, but its mechanics can be very frustrating to get used to. It seems like if you are above a character, they cannot shoot you so try to abuse that. The scoring system is score times combo if you lived and score times .25 times combo if you died. Your combo is determined by the greatest number of enemies you saw die while you had the glasses on. If you want a high score, you need to have a big combo since its really hard not to die and that 75% reduction is a killer. All of these are things I needed to figure out on my own since the game doesn't hold your hand at all.
