From the review:
Keyflower is a game for two to six players played over four rounds. Each round represents a season: spring, summer, autumn, and finally winter. Each player starts the game with a “home” tile and an initial team of eight workers, each of which is colored red, yellow, or blue. Workers of matching colors are used by the players to bid for tiles to add to their villages. Matching workers may alternatively be used to generate resources, skills and additional workers, not only from the player’s own tiles, but also from the tiles in the other players’ villages and from the new tiles being auctioned.
