Why the Game Avoids Game Over Screens
During development, Yoshi initially took damage and players could face traditional failure states. However, Yamamoto noted during play-testing that staff members would push ahead with investigations without worrying about damage, frequently getting defeated before realizing it.
To encourage players to take risks and try out all kinds of challenges without worrying about losing remaining Yoshis or triggering a game over screen, the team removed damage mechanics entirely. Nogami added that because the primary focus of the game is interacting with creatures and investigating them, penalizing mistakes with damage offered no real meaning.
Agency and Mid-Game Credits
The absence of damage and falling penalties was intentional to preserve player agency during investigations. This same design philosophy led the team to leave out standard stage goals, ensuring players wouldn't rush past secrets just to reach an end point.
Additionally, the game features staff credits placed in the middle of the experience. Yamamoto explained that this choice was meant to give players the feeling that the world is open to them much earlier than usual, mirroring the freedom gamers typically feel only after clearing a final ending.
