Hummingbird is an infinite procedural musical exploration game.
Built around a complex set of synthesizers and procedural behaviours and colour palettes, the world you encounter will be different each time you play.
Hummingbird comes with a 16-page pdf manual, and paying $10 (or more) will get you access to a 12-page pdf zine, each page of which is filled with dense, hand-lettered text originally generated by the game itself.
Physical (hand-bound) copies of both the zine and the manual are also available for an additional charge from the itch.io page.
See also the custom controller I built for the game.
