How to Play Casper
Quick start
Choose New Game and complete the tutorial before entering Level 1, The Manor. Casper must escort the sleepwalking Dr Harvey safely to each exit while the doctor continues walking ahead on his own. Fly through walls to reach switches and items, collect the required formula flasks, and use keys, glue buckets and Casper’s transformations to redirect the doctor or neutralise hazards. Watch his route before triggering a device: prepare the safe path first, then let him advance. The five main areas continue through the Manor Garden, Forest, Leisure Park and Laboratory.
Controls
The D-pad flies Casper in four directions and moves through menus. A confirms, interacts with nearby switches or objects, and uses the currently available transformation or item when its icon is active; B cancels or cycles back from the current choice. START pauses and opens the level menu; SELECT changes the selected transformation or inventory item when more than one is available. Follow the tutorial prompts for transformation-specific actions, because Casper’s six forms interact with different traps and obstacles.
