Thanks for the bug report! Found it: the puzzle generator had a "parity check" that only allowed clicking each tile once. On a 3x3 grid (9 tiles), this capped all puzzles at 9 moves maximum, even though levels 10-20 were supposed to require 10-20 moves. The root cause: We were using binary logic (clicked/not-clicked) in a game with 3-color cycling. With 3 colors, each tile can be usefully clicked up to 2 times before returning to its original state. fix v1.87.0: Changed from binary parity to tracking actual click counts, allowing each tile to be clicked (colors - 1) times. This enables up to 18 moves on a 3x3 grid, exactly as pyt correctly calculated! Now levels properly progress: - Levels 1-18: 3x3 grid (max 18 moves) - Levels 19-32: 4x4 grid (max 32 moves) - Levels 33+: 5x5 grid (max 50 moves) Thanks for playing!
