Osomatsu-kun: Back to the Me no Deppa no Maki — About this game
Osomatsu, who finds a hanging scroll depicting an ancestor with no buck teeth and something shiny on it, sets off on an adventure in a time machine with big bread. The setting is modern times, the Edo period, and the primitive era. On the city map, you can walk on your own, and inside buildings, you can advance the story by selecting icons such as investigating, listening to stories, thinking, and offering things. Familiar faces appear in different forms depending on the era, and even ordinary possessions can be useful in different situations. The energy meter decreases through actions and mazes, and when it reaches zero, the game is over, so it is important not to repeat dangerous interactions unnecessarily. At Kuroko's inn, record the password and organize the clues as you travel through time.
