4-Color Dungeon Bricks Extended (16x16)
An extension of my old 4-Color Dungeon Brick set, now with a variety of objects, furniture, and decorations for a castle or dungeon. Most tiles only use the three darker shades, reserving the lightest color for surfaces which the player can interact with (and sprites, if I ever make any).
