Aviary

The Aviary is a shop in Endless Doves that allows the player to unlock other flying creatures with the player's accumulated doves. It can be accessed from the game's menu and also from the game over screen (underneath the settings cog).

Overview
When the player accesses the shop, they will be able to browse through other creatures that can be unlocked and those already unlocked. Creatures that have yet been unlocked appear as a silhouette of that animal with a number indicating how many doves are required to unlock it; the name of the animal is also covered by question marks.

When playing the game, if the player dies but has collected enough doves to increase their total accumulated doves to the amount necessary to unlock an animal, a musical note (♪) in a speech bubble will appear next to The Aviary button. Unlocking a flying creature when the doves prerequisite number has been has been satisfied requires the the player navigate to The Aviary page for that animal and press the unlock button, where the animal's name and image will be revealed.

An unlocked animal can be used during the game, but only one at a time (as in no more than one animal can be active in the game at the same time). In The Aviary the player can toggle which flying creature appears when they play the game.

Animals to be unlocked
Each flying creature has an image of it in The Aviary, and when appearing in-game has a unique sound effect for being collected and a custom sprite.

Trivia

 * The amount of doves required for the chicken was changed during development. Originally it required 120 doves, but was later changed to 20 (see Endless Doves → Development changes).
