Modding guide

The mod title should be the same as the folder name
The game supports image of any size in PNG JPEG formats; each dimension must be, independently, a power of two
But, to avoid lag spikes while loading images, it's better to stick to recommended sizes in px
Suika skin sprite = 256-512
Suika ui icon sprite = 128-256
Container skin sprite = 256-512
In game background = screen resolution in 16:9, 18:9, 21:9 ratio
Loading screen background = screen resolution in 16:9, 18:9, 21:9 ratio
Loading icon = 128-256
Character skin = 128-512
The game supports audio files in MP3 WAV OGG formats

Modding tool

Look at an example mod in StreamingAssets folder
