The assets and concepts I produced for the crystal cave biome, for the game Lightless by Ghoul Rot Games.
I went for a Hollow Knight looking art style.
Most of the assets are intended as background or foreground only (basically, decoration). Some, like the certain crystals, will emit light after their integration in game.
The demo version of Lightless can be played here : https://ghoulrotgames.itch.io/lightless
