Here's how the game "saves" your progress:
* Auto-Save: The game automatically saves your progress at certain key points in the story, typically after major events or conversations. This means you don't need to manually save.
* "Checkpoint" System: When you turn off the DS, the game will remember your progress up to the last "checkpoint".
Important Notes:
* No Battery Backup: Unlike some games, Hotel Dusk does not use a battery to store your progress. So if you lose your save file, you'll have to restart the game.
* Be Careful: Don't turn off your DS or close the game unexpectedly as you may lose progress.
Overall: Hotel Dusk relies on a unique "save" system that relies on checkpoints and auto-saving. While you can't manually save, the game does a good job of preserving your progress as you play.
