Time and Eternity , a role-playing game set in the kingdom of Kamza, follows Princess Toki as she relives her wedding over and over again after being mortally wounded by a sudden attack. Her hidden power allows her to travel back in time, merging events from the past and present. The player must guide Zack through his choice between marrying either Princess Toki or Towa, another part of her soul.
The game features hand-drawn anime style animation for character cut-scenes, battle sequences, and world exploration. Gameplay involves timing actions to evade enemy attacks, blocking them, and powering up counterattacks during in-game battles.
