Gameplay

Top Hat Willy is similar to Jet Set Willy. It has three controls: left, right and jump. Willy can climb stairs by jumping onto them (walking through them to avoid them). The play area itself consists of 100 rooms containing patrolling monsters, various platforms and 160 collectable objects. The collectable items glow to distinguish them from other items in the room.
