# The Unicorn and the Foul Pattern > The Pattern that was never meant to exist This game is my second venture into the fantasy world of The Chronicles of Amber by Roger Zelazny. My first is the obscure entry from 2018 - Storm of the Chaos Bane. The main protagonist here is the Unicorn - the primordial mother of Order.

Solve 3 puzzles to reach a Vail, then fight a turn-based tactical battle. In the final Vail, you face Brand himself. ## Arcade Solve 100 puzzles of increasing difficulty. ### Puzzles Guide the Unicorn, leaving a rainbow trail with every step. Surround enemies with the trail to capture them. You cannot cross your own trail - stepping onto it undoes your moves back to that point. Each puzzle contains a Jewel. Collect it and reach the sparkling exit. In Campaign, some stages contain imprisoned heroes that you must surround to rescue. Enemies left on the puzzle stages are carried in the upcoming Vail battle. ### Turn-based combat The Unicorn moves like a chess knight. With the keyboard, use two arrow presses to aim the L-shaped jump: first choose the long leg, then the direction of the step. Heroes and enemies have different attack / movement schemes, marked with chess abbreviations: - **R** - Rook, horizontal / vertical - **B** - Bishop, diagonal - **K** - Knight, L-shaped For example, **R2** means an attack or move with a range of two orthogonal tiles. ## Controls Mouse / Touch: Click / Tap / Swipe to move select or attack Keyboard: Arrows / WASD Space: attack enemies in range Enter: end Unicorn's turn early Tab / Shift+Tab: Cycle through player / enemy stats Esc: Pause.
