Magic bird is a game about a magical bird that needs to go on an adventure to lay its egg. 

The game is an adventure game, where the player will move a little bird around a large grid. 

The player will explore the map, looking for X number of necessary, collectible items. Once those are found, the player will navigate the bird to the target location, where it'll use the collected items to make a nest and lay its egg, thus completing the game. 

As the player navigates the world they will travel default space (like fields), forests, mountains, and towns. 

In each different space the player has a different chance of encountering a type of guy. 

Possible types of guy: 

- A human child
- A hunter
- A bird watcher
- An ambler
- A wizard
- A witch

When the player encounters a type of guy, the encounter menu is triggered. The player can choose 1 of a few actions: 

- Evade
- Feather
- Kill

If evade is selected the player and the guy roll, if the player beats the guy's evade score, the bird gets away unnoticed and unharmed -- a neutral outcome. 

If feather is selected, the player gifts the guy a magical feather from the bird's own body. The guy leaves, placated. The bird only has a set number of feathers, and cannot get more. Once all of the feathers are gifted, the player looses the game. Feathers are precious, and not easily parted with.

If kill is selected the player kills whomever they've encountered. There is no roll or contest. The bird can kill anything, no matter what, but, if the bird kills too much, the bird won't be allowed entrance to the sacred mountain at the end of the game where it must lay its egg, and therefore cannot complete the game. Gifting feathers undoes the kill count by 1.

Map maker, also in this repository, was made to make it easier to make maps for magic bird.
