Deepvein — Mining Platformer Tileset

A complete set for building 2D platformer levels underground.

Three looks - warm sandstone caverns, pale limestone hollows and a buried temple of dressed stone - plus a near-black deep stone shot through with gold veins. Every material carries a full 47-tile autotile edge set, so straight edges, outer corners AND inner corners are all covered. Drop the atlas into your tilemap, use the included lookup table, and the edges resolve themselves.

WHAT'S IN IT

- 10 tileable materials, each as a 47-tile autotile atlas at 256 x 256 px: sandstone rock (two paintings), sandstone background, temple masonry (two paintings), packed earth, limestone (two paintings), limestone background and gold-veined deep stone

- 160 props across ten categories: crates, barrels, chests, tools and bombs; treasure, crowns, idols and gemstones; mushrooms, bones, roots and stalagmites; crystals and ore veins; carved idols, columns, statues and altars; ladders, scaffolds, carts and bridges; spikes, levers, saw blades and cages; grass, moss, vines and ferns; cracks, stains and mineral seams; fossils and limestone ruins

- 5 looping animations, 8 frames each: torch, brazier, stone brazier, lantern, crystal glow

- One character illustration for your title art

- index.json with every file, its size and the autotile lookup

BUILT FOR REAL USE

Every tile carries its own lit top edge, dark outline and interior depth shading, so terrain reads correctly with no engine lighting at all. Add 2D lights on the torches and crystals and you get the look in the screenshots.

Straight alpha PNGs. No proprietary format, no plugin, nothing to install.

AI DISCLOSURE

Source imagery was generated with OpenAI GPT Image from written prompts, then processed with purpose-built tooling that is not part of the generator: chroma keying with alpha-weighted key unmixing, automatic grid splitting, exact rescaling to a fixed size table, and the complete terrain edge treatment - the 47-tile autotile set, uniform outline, lit rim and depth shading are computed from the tile neighbourhood, not generated. All animation frames are computed from a single still by deformation, not generated.
