Made for game logic

• Every sprite as its own PNG and on a sheet per group with a JSON map, at 1x, 2x and 3x, plus palettes and a README.
• The JSON gives each generator its tier, each rarity piece its rarity, each animation its frame count, fps and loop flag, and each UI piece its 9-slice margins, content rect and icon socket.
• Exact grids: icons are 32x32 and stay 1 px inside their cell; UI pieces are multiples of 16; the build checks that every 9-slice stretch area is flat and that the bar fills sit exactly in their frame.

What it does not include

No characters, backgrounds or sound, no engine project or Aseprite files, no TTF (the number font is a bitmap font). The labels in the screenshots use our preview font, which is not included. The art is drawn at 1x; 2x and 3x are scaled copies.

Licence

Use and modify in personal and commercial projects. Shipping the sprites inside your game is fine. No resale or redistribution of the assets, modified or not. Credit is appreciated, not required. Not for AI training or NFTs.

How it was made

Every sprite is drawn by code (Python): shapes placed on the pixel grid, shaded from the top left onto small colour ramps and outlined; the UI is built ring by ring. No image generator, no third-party art. The drawing code was written with AI-assisted tools, which is why the page is tagged AI Assisted.
