About SKEIN
About SKEIN
SKEIN is a short action game about leading geese south through a night sky. It uses pixel art, music, and a nature focused setting to shape a quiet flight with changing weather. The game was made by Core Systems Asset Factory for thatgamejam #02, whose theme was a piece of music. SKEIN runs in the browser on itch.io and is listed as free. A Windows build is also available to download.
Gameplay and choices in SKEIN
You begin alone and search the clouds for six other geese, bringing them into your line. The lead bird tires while the birds behind it recover in its wake, so you decide when to hand over the lead. Timing that handover with the music keeps the line together; mistiming it briefly breaks the formation. Wind, rising air, rain, and cloud affect the flight. Each journey lasts about three minutes, and how many of the seven geese reach home depends on your choices.
What sets SKEIN apart
SKEIN builds its flight around a piece of music: the pulse sets the wingbeat, and the game’s three acts follow the music’s shape. The score was written for the game rather than using the jam track. Its central fantasy is modest but clear: gather a flock, hold formation, and guide the birds through night weather toward the sea at dawn. For strategy fans, the lead handover adds a simple timing choice to the action without suggesting a larger build system.
Is SKEIN for you?
SKEIN may suit players who enjoy atmospheric nature themes, pixel art, and a focused fantasy of guiding a flock through one short flight. Strategy fans can engage with timing and formation decisions, while players seeking heroes, classes, or deep upgrade builds may find little here: the listed facts describe no such systems. The game is released, not identified as a demo, and a flight takes about three minutes. It is singleplayer and runs in a browser on itch.io.
