How to Play Bugs Bunny in Crazy Castle 4
Quick start
Start a new game and inspect the first room. Choose the nearest safe key route, wait for enemies to clear the passage and return to open space before planning the next key.
Controls
Use the D-pad to guide Bugs Bunny and navigate available ladders and passages. A confirms menu choices, B cancels where offered. Follow the stage's instructions for any item use; movement and route planning are central, rather than relying on a standard jump attack.
Bugs Bunny in Crazy Castle 4 — About this game
Look over the room before moving toward the first key. Notice enemy paths and leave a way back from ladders and dead ends. Collect one key at a time while checking how the safe route changes; this is a navigation puzzle, so patience helps more than assuming every threat can be beaten head-on.
