AI play and a live walkthrough

The English player now has optional AI play. An on-device planner chooses its own story route, navigates the city and answers interviews. Start it after name entry, pause it, or take over with a game button or controller. Normal and 3× speeds are available. It uses a local game planner; no cloud account or language-model service is required.

The side walkthrough follows the current date and story route. Once the game confirms a task and its scene finishes, the task moves from To do into Completed. You can also mark tasks manually and undo today’s checks. Manual marks stay distinct from verified game progress. Checklist history is saved in this browser; restoring a game snapshot clears the discarded timeline and checks the restored day again.

The same JavaScript planner reached all three story-group endings in a native SNES test adapter, with twelve credit pages on each path. Browser testing separately covers live navigation, automatic and manual checklists, snapshots, pause and taking control. Exact methods, additional choice coverage and physical-controller limits are in the test record. These checks do not enumerate every combination of optional choices.

The cartridge remains English 1.0.2, so existing 1.0.2 snapshots keep their identity. The original Japanese edition, older English players, audio and graphics archives remain available.
