Please be as specific as possible when letting us know what is missing or incorrect. For example, say "this game's trophy difficulty should be 8/10", with a link to a website corroborating this difficulty estimate (if possible), not "this game's trophy difficulty is wrong".
Instant Death is a First-Person hardcore reflex game. Your goal is to complete the level without touching the color red. If you touch anything red you're DEAD. Also, be careful and don't rush unless you're very confident in your skill since there are no checkpoints in the levels.
