About SKEIN
What is SKEIN?
SKEIN is a short action game about flying geese. Lead a skein south through one night and find the birds calling from the clouds. CSAF — Core Systems Asset Factory — made it for thatgamejam #02. You can play SKEIN in a browser on itch.io with keyboard, mouse, touch, or a gamepad. It is a released game, and one flight lasts about three minutes.
How a run of SKEIN plays
Start alone at dusk and search the clouds for the other geese. Beat your wings to gain lift, then guide the flock through wind, rain, and cloud. Birds behind the leader recover in its wake while the front bird tires. Hand over the lead on the music’s pulse to keep the line together. A spent bird comes down to rest, and the flight continues without it. See how many of the seven come home.
Why SKEIN is worth a try
SKEIN shapes its flight around music: the score’s pulse sets the wingbeat, and the game moves through three acts shaped by the track. The front bird works hardest while the others recover in its wake, as long as they hold the line. That makes each handover a rhythmic choice. A flight takes about three minutes, keeping the focus on one compact journey through the night.
Who will enjoy SKEIN
SKEIN suits players who enjoy short action games, music-led atmosphere, and a simple score to chase: how many of the seven geese will make it home? Each flight lasts about three minutes, so it fits a quick browser session. Expect an atmospheric flight with weather and a flock to guide. It is released, and its loop centers on flying together rather than collecting monsters or upgrading between runs.
