The Doppel is a classic side-scrolling action game, but differs from many others in that it features only one enemy.
The sole enemy, “Doppel,” appears exactly like you and tracks your movements precisely as it pursues you.

As a writer pushed to the edge of their career, players must flee from Doppel while reflecting on their roots and confronting hidden fears within themselves.

All graphics in The Doppel are composed solely of two-colored pixels.
The minimalist yet beautiful world, stripped down to its essentials, will help spark your imagination.
