Beach gameplay
Overview
Beach is the reflection world. Diagonal beams bounce off board edges once before stopping. A bishop placed near a corner can cover squares it would never reach on a normal board. Only bishops and queens appear here because the reflection mechanic only applies to diagonal movement. Rooks, knights, kings, and pawns would not benefit from it.
The Mechanic: Beam reflection
Beach makes diagonal beams bounce off board edges. When a bishop or queen's diagonal ray hits the edge of the board, it reflects once (like a billiard ball) and keeps going. Orthogonal rays (rook lines) are unaffected. This single change massively expands diagonal coverage and creates puzzles where you need to think in bank shots. Only bishops and queens appear in this world because the mechanic only affects diagonals.

Level progression
Starts with single-bishop puzzles to teach the bounce. Moves to single-queen, then multi-piece combinations. Later levels add blocked cells to constrain solutions.
