An animated pixel art short in one Aseprite file
The heroes came through last night. Now the skeleton janitor has to clean up the goo, the arrows, the coins and a very hungry mimic. Every sprite was drawn new for this short.

What makes it work
Inside the file
- Cleaning is literally a layer emptying out: the Mess layer holds everything the heroes left.
- Light is layers too: a multiply Shade layer, Lights, and an additive Glow.
- Everything that moves lives on tilemap layers, so a 512-frame file stays small.
How it was built
Step by step
- Rig and drawThe janitor, the knight, the slime and the props, each on named layers.
- BuildStep by step through SpriteRelay CLI, compared with the design after every step.
- ExportsThe 512 final frames and five layers exported on their own.
