+# Room 098: Transitional Room
+
+This is a simple transitional room that automatically moves the player to room 698 after a brief delay. The player enters from the left side and walks across the screen while a timer counts down. This appears to be a bridge or cutscene transition between areas.
+
+## Look Description
+
+This room has no interactive elements or distinct look description. It serves purely as a transitional space where the player character automatically walks across the screen before the game advances to the next room (698). The lack of a handleEvent method means no player interactions are possible in this room.
+
+## Interactions
+
+This room has no interactions defined. The player cannot look at, get, or interact with anything in this room.

+|--------|--------------|------|---------|----------|
+| TODO | Background | AutoWalk | Room initialization | Player enters at position (20, 99) and automatically walks to (300, 100) using MoveTo motion and Fwd cycle |
+| TODO | Background | TimerTransition | After global222 > local0 | Tracks frames elapsed (global222), adjusts game speed (global223), and transitions to room 698 when timer expires |

+### State Variables
+
+| Variable | Values | Description |
+|----------|--------|-------------|
+| `global222` | incrementing counter | Tracks number of frames since entering the room |
+| `local0` | computed value (60 + initial time) | Threshold value for timer; set on first frame |
+| `global223` | 0, 1, 2 | Controls game speed during transition: 0 (fast) for first 30 frames, 1 (medium) for frames 30-60, 2 (normal) after 60 frames |
+
+### Timing Logic
+
+The transition timing works as follows:
+1. On first frame (global222 = 1): local0 is set to current time + 60
+2. Each subsequent frame: global222 increments
+3. When current time exceeds local0: transition to room 698
+4. During transition: game speed changes based on how much time has passed (affects animation smoothness)
