Rubas' palace is presented in one-point perspective. The screen scrolls sideways only, except in bell towers, where the screen scrolls vertically. Prince Myer can walk in eight directions, and attacks by throwing a sword. The player earns coins (a currency called ludder) by killing monsters, and can trade ludder at shops in the palace for new equipment. The shops are in fixed locations throughout the palace, but the inventory may change.
The palace is vast, and has ten labyrinthine dungeons. The first dungeon-maze has 167 screens, and the tenth has 235.[5] Seven of the ten dungeons leads to a bell tower, at the top of which is a boss.
Hidden throughout the palace are invisible portals to a secret area called the Parallel Zone, where the player can find equipment superior to that available in the shops.
