HiddenAttack (FPS + AR Game)

If somebody else picks up your phone and sees this app it will just
look like a regular note-keeping app. But they are actually seeing
a bunch of bogus notes. Draw any squiggle to make the unlock screen show.
When you enter the correct unlock pattern the bogus notes
are hidden and your real notes are displayed.
