Cuckoo! is a game about merging birds together to make them as big as possible, before setting them free and collecting their points. It is casual, easy to learn and fun to play.

Here's how it works:
* Swap two birds by dragging them in the wanted direction. You can only swap two birds at a time, and only if they are perfectly aligned side-to-side or top-to-bottom.
* Two birds of the same species that would form a perfect rectangle together will merge into one bigger bird.
* Quickly tap a bird twice to set it free and collect points. This can only be done if a bird is big enough.
* Some birds can be set free smaller than others: sparrows only need to be two squares and halcyons only one. All other birds need to be 3 squares at least.
* A 2 by 2 bird will for example generate more points in comparison to a 4 by 1 bird, despite being the same size.
* Birds prefer merging horizontally.
* Special combinations of birds on the field can unlock new skins for your birds.

Please keep in mind that this is my very first app, and I pretty much ignored every convention out there. I apologise if the app feels buggy or glitchy, but my friends and family seem to have a great time playing it, and I hope you will too.
