This page lists the IDs for every map in the game, as well as the author who reserved them, the world it is associated with, and whether it is accessible or not.
Each map can be viewed in the editor by opening RPG Maker 2000 or RPG Maker 2003 and opening the "ゆめ２っき" folder which contains all of the game's assets, all of the map files, and et cetera with the "Open Project" function in the "Project" tab. From there, each map is open for selection in the column on the left. (it is important to note that almost all of the game's maps are sub-maps of other maps, and can only be viewed by clicking on the [+] on the side of each parent map)
There are five possible statuses for each world:
- Accessible - Can be accessed while dreaming without editing the game or playing in Playtest Mode
- Accessible While Awake - Can be accessed while awake without editing the game or playing in Playtest Mode
- Inaccessible - Cannot be accessed without editing the game or playing in Playtest Mode
- Unused - Has been reserved, but not edited by its author
- Non-Walkable - Accessible, but denies direct control of Urotsuki
Only worlds that are labeled Accessible contributes to the game's map visited percentage, which is viewable as it is equal to the number of dreamdollars that Urotsuki recieves when breaking open her piggy bank in her dream room.
(NOTE: Playtest Mode is where you run the game using the "playtest" function while the game is open in RPG Maker. It allows you to activate Debug Mode, which in turn allows you to instantly teleport to any map in the game given you know its ID)
