This movie improves all rejected submission on each levels using more tricks documented by me on the GameResources/NES/Shinobi page.
The route is going to right, avoiding the BONUS STAGE powerup (which is a minimum 25 second ninja shooter mini-game which gives you one of the totally worthless ninja magics out of 5 I guess) and only picking up POWER UP power up to kill the blue ninjas with 3HP (at very later levels).
You guessed it right. The game sucks. See you until my next TAS =)
