The objective in Ninjufo is to pilot a UFO craft around a maze and collect fifty crates with top secret information contained inside them. Shurikens can be used to destroy enemy ships, although this has to be done without them spotting you first as their shots are near impossible to dodge.

Some money is deducted from your haul whenever your ship is destroyed, but the penalty is hardly a concern unless you are planning to submit a good score online.

Play it on Newgrounds or Armorgames.
