Elizabeth Hargrave had begun work on Mariposas, a game about migrating monarch butterflies in 2018, and she sold it to game publisher Alderac Entertainment Group (AEG). This marks the beginning of the development of another of her games, focusing on a specific aspect of nature, the monarch butterfly migration. It is impossible to pinpoint the exact date when the game was created, so the first day of the year is chosen for this entry.
