Custom Spiribirds will let you set a custom value for each of the four spiribird buff types, ranging from health between 1 and 50, stamina between 1 and 50, attack between 1 and 15, and defense between 1 and 25. You can set the value of each buff type to whatever you want, and it will save automatically.

Each setting will also save the original petalace value if you wish to keep that.

The reason why Custom Spiribirds is like this is because I felt that the values were not really being used in the game, and it was just a hack to make the game a bit more fun. The idea is to have a custom petalace for each of the four buff types, and the reason for that is: I like the idea of the petalace, but I wanted it to be more than just a number. I wanted the player to have a reason to look for the petalace, and I wanted the player to have a choice as to whether they would look for the petalace or not.
