I can see the right blue guide wall was changed. Looking at lines 694-707, the right guide wall length was shortened from 1.8 to 1.3 and repositioned. The changes are: - **Length**: `rightGuideLength = 1.3` (shortened from 1.8) - **Position**: `(this.tableWidth / 2 - 0.1 - 1.4, guideHeight / 2, this.tableHeight / 2 - 1.5)` - moved to avoid intersection with the main wall The change prevents the right guide wall from intersecting with the main outer wall while still providing ball guidance toward the flippers.
