If you have having trouble completing the game, try these tips:

- Resources in this game are limited once you get strong enough,
  try to use your knife as much as possible.

- There is no save feature, so you'll have to play through the whole
  game in one session, this also means.. you don't want to die. So
  use a nanohealer when you get low on HPs.

- Some enemies will have items they may drop for you to get.

- Don't fight Karl until you are stocked up on nanohealers, or have
  a good supply of genades.
