Arroway

## Description

_Arroway_ puts a certain spin on the classic sliding puzzle. The board
consists of sliding tiles, each of which features an arrow. Clicking the tile
turns the arrow around, and if three arrows in a row point in the same
direction, they are eliminated. Due to the interlocking nature of the arrows,
it is rarely possible to eliminate all tiles just by turning the arrows,
forcing you to start sliding the tiles around. As the game progresses, bonus
crystals appear on the board, and can be taken only by sliding the empty tile
into them.
