In the game, pressing R+S allows for a restart, and movement is carried out using the directional pad. Pressing the I key is used for dialogue and casting spells, while the II key is used for investigation and speeding up text messages. The R key can access the sub-screen, and the S key is used for equipment and selecting treasures.

There are also hidden cheats in the game, primarily as follows:

To avoid enemies in combat or surrounded situations, enter the storage screen and return to the normal screen. Enemies will disappear during this time.

After getting poisoned, save immediately and restart the game. When entering the saved memory file, you will find that the poisoning status has been lifted.

The treasure chest on the left upper side of the first floor of the Rainbow Tower contains herbs. After using herbs, open the chest again, and surprisingly, herbs will appear again. Doing this a few times significantly boosts health.

Obtain the spell "らいめい" (Thunder) inside the Rainbow Tower. Equip Thunder on floors 1, 2, and 3, then go to the far left of the tower and use it. This will cause enemies on the right side to disappear after undergoing a penetrating attack.
