### Workflow
1) ``OverworldLoop`` is called from ``GameMenu_WorldMap`` with either ``hMapEntryMethod`` = ``MAPSETUP_ENTERLEVEL`` or ``hMapEntryMethod`` = ``MAPSETUP_CONTINUE``.
2) ``StartMap`` resets ``wCurTurn`` and ``wCurSpace`` if ``MAPSETUP_ENTERLEVEL``. ``StartMap`` sets ``hCurBoardEvent`` to ``BOARDEVENT_DISPLAY_MENU``. ``wScriptFlags2`` is cleared. ``wMapStatus`` is set to ``MAPSTATUS_HANDLE`` causing ``HandleMap`` to be called.
3) ``MapEvents`` (from ``HandleMap``) calls ``PlayerEvents``. ``CheckBoardEvent`` queues ``BoardMenuScript`` which is executed by ``ScriptEvents``.
4) ``BoardMenuScript``.``Upkeep`` saves the game, clears ``wTurnData[]``, increases ``wCurTurn``, and loads current space to ``wCurSpaceData[]``.
4) ``BoardMenuScript``.``Upkeep`` saves the game, clears ``wTurnData[]``, increases ``wCurTurn``, and loads current space to ``wCurSpaceStruct[]``.
- If player exits, the ``exitoverworld`` script sets ``wMapStatus`` to ``MAPSTATUS_DONE``. This causes ``OverworldLoop`` to return back to the game menu. **Exit this workflow**.
5) Player rolls die and the animation plays. After the animation, ``wDisplaySecondarySprites``.``SECONDARYSPRITES_SPACES_LEFT_F`` is set and ``hCurBoardEvent`` is set to ``BOARDEVENT_HANDLE_BOARD``. At the end of this ``HandleMap`` iteration, ``CheckPlayerState`` sets ``wMapEventStatus`` to ``MAPEVENTS_ON`` (``wScriptFlags2`` is not touched so it remains cleared).
6) In the next ``HandleMap`` iteration, ``CheckBoardEvent`` from ``PlayerEvents`` jumps to ``.board`` and then to ``.no_space_effect`` due to ``wScriptFlags2[4]`` not being set.

10) In the next ``HandleMap`` iteration, ``CheckBoardEvent.board`` is called with ``wScriptFlags2[4]`` set.
- If player is not above a tile (``wPlayerTile``) with a space collision: ``wScriptFlags2[4]`` is reset. **Go back to 7)**.
- If player is above a tile, the corresponding space script is queued to be executed by ``ScriptEvents`` in the current ``HandleMap`` iteration. ``wScriptFlags2[4]`` is reset. **Continue to 11)**.
11) The space script loads the value of ``wCurSpaceNextSpace`` into ``wCurSpace``, loads the new space data to ``wCurSpaceData[]``, and decreases ``wSpacesLeft``.
11) The space script loads the value of ``wCurSpaceNextSpace`` into ``wCurSpace``, loads the new space data to ``wCurSpaceStruct[]``, and decreases ``wSpacesLeft``.
- If ``wSpacesLeft`` is non-0, **go back to 6)**.
12) ``hCurBoardEvent`` is set to ``BOARDEVENT_END_TURN``. ``CheckBoardEvent`` does nothing in this state. In the first subsequent ``HandleMap`` iteration where no other kind of event triggers causing ``PlayerEvents`` to return early, ``hCurBoardEvent`` is set to ``BOARDEVENT_DISPLAY_MENU``.
13) **Go back to 3)**
