There are some shortcuts in the game that let you proceed without finishing a Puzzle. There is no penalty for finding and using a shortcut if you are clever enough to discover one.
The camera isn’t perfect and will occasionally not show the character or pass though objects or structures. If this happens, try to jump or move around. This should restore the camera angle.
On the rare occasion that you fall through a hole in the map, you should eventually respawn in an area near the map hole once you run out of health. If this doesn’t happen, you will need to restart the level.
Combo Attacks are more about how they look than what they do. In other words, Combo Attack upgrades don’t do more damage, but they look cooler.
You will sometimes encounter a Destructible Door that is hiding collectible items such as Pages or Memorabilia.
Destructible Doors can only be opened by certain characters. Sheets pinned to the doors will give you a hint as to which character or characters can open each door.
