Retro game icons
heartpotionswordHearts, potions, swords, and coins: the inventory items of a childhood.
The classic game icon set is the style's alphabet, and original designs in that language avoid any copyright headache. A three-heart health bar or a tiny potion bottle carries instant recognition with a personal twist.
Best for wrist-adjacent forearm, ankle, and behind the arm, where a small grid sits flat.
Keep the palette to three or four flat colors plus a dark outline pixel row. A tiny white shine pixel in the corner sells the whole sprite.
