Zugzwang is a tactical first person gay sex dungeon roguelike about amassing body fluids.

by Robert Yang (debacle.us@radiatoryang)

Desire is a labyrinth. As a sex angel, you must help mankind meet each other in the neon darkness. Drink deep their juices, distill their pleasure into divinity. The absence of the witch does not invalidate the spell.

A gay chess-puzzle game inspired by sex magic, the history of censorship in the US, architecture, and the poetry of Emily Dickinson.

>> For more info on the history and inspirations (as well as hints), read my artist statement: "Zugzwang as a pole dance upward unto heaven."
