Aspic: Majaou no Noroi — About this game
Samson obtains the Book of Truth to break the princess's curse, and upon his return, he learns that the princess is about to be forced to marry Aspic, the demon serpent king. The rescue journey continues from the human world to the sea and sand world, and then to the demon world. On the ground, you walk along a map that looks down on you, and when you enter a building, it turns into a three-dimensional labyrinth that you advance step by step. Jump over holes and find the tools you need to move forward. When you encounter an enemy, you can choose to fight, talk, or run away, and in battle, decide which of your friends will appear and take on the horizontal screen action using swords and magic. In addition to gaining experience and increasing your attack power, it is also important to manage your magical power and recovery methods. Memorize dead ends and locked doors, and use items available in multiple worlds to clear your way.
