Every sprite and backdrop

The one-shot prompt that made the game playing below. The highlighted part asks Logospell for the sprites and the backdrop: 3 credits, exactly the 3 free ones new accounts start with.
the prompt we gave Claude, verbatimBuild me a side-scrolling night shooter as a single index.html. I play a firefly in the dark, and my glow is both how I see and my health: every hit dims it and shrinks the circle I can see. […] Use the logospell MCP server to generate ONE transparent image set of 32 sprites in two calls of 16, all in one style: the painted and gilded leather figures of Javanese wayang kulit, drawn without their rods. The first call: the firefly flying and the firefly flashing with its wings thrown wide (both facing right), a gunungan (the tree-of-life figure a shadow play uses to change scenes), the storm cloud pickup, and for the meadow 5 flying enemies, 2 ground enemies and the barn owl boss (all facing left) plus 4 pieces of meadow scenery. The second call extends that set, using sprites from the first call as style references: the other 3 pickups, and for the swamp 5 flying enemies, 3 ground enemies and the crowned bullfrog king boss (all facing left) plus 4 pieces of swamp scenery. Then make one illustration in the same style: a very wide night panorama that runs from the meadow under its low moon on the left to the moonless swamp on the right, with no creatures in it.

What came back: 32 sprites in one style, 16 per call, and the panorama behind them, the exact files the game runs on.
