Hugo Alone in the Tower Walkthrough

1.after every level if there is a gun buy it
2.use the rocket only when there is a bunch of enemies
3.keep beating the enemy until he dies dont go to other until he dies

Make sure to move back and forth to cover both sides.

Also, going for head shots will cause the double damage, which is good, but later on in the game, it's better to just mow them down and not worry to much about headshots.
