How to Play Bugs Bunny: Crazy Castle 3
Quick start
Press START at the title and choose Start for a new game. Begin in the Garden, enter rooms and search for all eight keys. Up and Down handle doors, ladders and other passages. If a rival blocks the route, use a collected defensive item with A or B. Once the key count reaches eight, return to the locked exit. Record the stage password for later.
Controls
The D-pad moves Bugs and uses doors, stairs, ladders, vines and pipes. A or B uses an item or activates a switch. START pauses; while paused, use the D-pad to look around the stage. SELECT is unused. With a hammer or pickaxe, move toward the appropriate special block to use its effect.
Bugs Bunny: Crazy Castle 3 — About this game
Some rivals follow Bugs while others patrol a fixed area, so watching their movement helps you decide which passage to take. Bombs, cork guns and pushable weights can clear a route, while a hammer or pickaxe opens possibilities around special blocks. Pausing lets you inspect the stage with the D-pad. Use that overview to locate missed keys and avoid entering a room without a way past its waiting enemy.
