There are 8 total characters that should be included in a single image strip. Each character tile is 96×96.

All 8 tiles must be in a single PNG image where each 96×96 tile is arranged horizontally resulting in a 768×96 image. PNG is used as alpha transparency is supported.

Each tile forms a character slot that can be referenced in the game. If you don't need 8 characters, it doesn't matter what is in the tile. But, you must still create a 768×96 image.
