Isometric Dungeon & Caves

A pixel art isometric dungeon, cave and mine: 337 pieces on the exact 32x16 diamond grid of Gridwright Isometric Tiles: rock, dirt, moss, crystal and volcanic ground, ore in the ground and in the walls (coal, copper, iron, silver, gold, gems), mine rails that join by themselves and mine carts, cave water, acid and magma with a waterfall and a lavafall, dungeon rooms with cut-away walls, prison cells, doors and a portcullis, chests that open and a mimic that bites, traps, glowing crystals and mushrooms, and three entrances for the overworld. Every standing piece has its own shadow sprite. For dungeon crawlers, roguelikes, tactics games, mining and colony sims.

Licence in one line: use it in your commercial games; do not resell the files. No credit required.

What you get

• Ground (30 blocks, 18 floors, 12 ramps and stairs): cave rock, cave dirt, dungeon stone, mossy cave, crystal rock and volcanic rock (lava glowing in the cracks); 3 blocks, a half block and 3 floors each; 6 ore blocks; ramps and dungeon stairs in 4 directions.
• Liquids (40 frames): animated cave water, bubbling acid and magma, each as a block and a floor, and a waterfall and a lavafall for the left or right face of a cliff; 4 frames each.
• Mine rails (15): straights, curves, junctions, a crossing and track ends, picked by neighbour mask (the JSON and README say how), so any track joins.
• Walls (58): natural cave rock with a rough top, dressed dungeon stone and timbered mine walls; full and cut-away pieces, doorways, corners and end posts; dungeon barred windows and prison-cell bars; cave walls with ore veins in 6 ores.
• Doors (24 frames) and wall decor (28): a wooden door, a barred cell door and a portcullis that rises, 4 frames each; hook lanterns (unlit and lit), wall levers that move, shackles, a chained skeleton, a crystal lamp, hanging roots and a tool rack.
• The mine (27): mine carts (empty, coal, gold, gems) along both axes, rail bumpers, timber supports, dynamite and ore crates, a powder barrel, a pick in a rock, ore piles, a lamp post (unlit and lit) and a winch over a shaft.
• The dungeon (57 with the frames): wooden, iron and gold chests and a mimic, facing both ways, opening in 4 frames; gold and gem treasure; a spike trap and a fire trap (4 frames), pressure plates, a trapdoor shut and open, a pedestal with a glowing orb, weapon racks, straw beds, a bucket and a hanging cage.
• Cave nature (22): stalagmites, a rock column, crystal clusters in 4 colours, a giant glowing mushroom and mushroom clusters, boulders, rubble, roots, a puddle and a moss patch.
• Entrances (6): a cave mouth, a mine headframe over its shaft and a dungeon gate with stairs going down, 2x2 cells, opening left or right (drawn both ways, not mirrored), to put on an overworld map.
• 49 shadow sprites: nothing is baked into the art; each standing piece has its own shadow with the same anchor.

Made to drop in

• The same grid as our other isometric packs: 32x16 diamond, 16 px blocks, every file a multiple of 16 px. It mixes with Isometric Tiles, Isometric Characters and Isometric Monsters.
• One JSON for everything (isometric.json): footprint, anchor, height, facing, frames and rail joins, plus the placement formula and the draw order in the README.
• Dark-ready: lanterns, fire, lava, acid, crystals and glowing fungi use their own colours, so a simple darkening shader keeps them bright, as in the screenshots.
• Clear names: rail_07.png, minecart_gold_nwse.png, chest_iron_se_f3.png, wall_cave_nw_ore_gold.png, portcullis_ne_f2.png.
• Single PNGs and sheets at 1x, 2x and 3x, and the palette (.hex, .gpl).
• The maps in the screenshots were put together from these same sprites.
