How to Play Bugs Bunny in Crazy Castle 4
Quick start
After the opening story, press A on the world map to enter Forest 1-1. Climb the first ladder and enter the door for a chest and key, then search the next rooms in the same way. Push the acorn bomb toward the nearby skunk to clear the path. Climb the vines for the last keys and return to the locked door once you have eight.
Controls
The D-pad moves Bugs, climbs ladders and vines, and enters doors with Up. A switches between the pop gun and balloon; B uses the selected weapon. START or SELECT pauses, and the D-pad then lets you inspect the surrounding stage. On the world map, A enters a stage.
Bugs Bunny in Crazy Castle 4 — About this game
The pop gun and balloon serve as limited defensive resources: choose one with A and use it with B when a pursuer threatens the route. Mushrooms can launch Bugs to higher platforms, and pushable acorn bombs offer another way to deal with enemies. Pause to look over the surrounding stage before committing to a descent. Reaching the exit is only useful after every key has been recovered from the rooms.
