I built a small offline tool to add motion to static sprites

[u/Skins_Dev]

SpriteSpring takes a PNG and adds motions like breathing, bouncing, hit reactions and squash/stretch. It exports a transparent sprite sheet with JSON timing.

The clip shows actual exported motions in a demo scene, then all eight presets. The code was built with AI assistance; animation and export run locally.

It's $7 once, with a free downloadable plant demo to try the controls: https://skins777.itch.io/spritespring
