The key is one of the oldest puzzle objects in games, and it still works because it is instantly readable: find this, open that. This collection gathers key and lock art across the catalog, from ornate skeleton keys and colored keycards to padlocks and keyrings for inventory screens. Use a key as the item that unlocks a door, a collectible that gates a path, or a color-coded puzzle in a dungeon where each key opens its matching lock. Drop a key into Summer and ask the engine to add it to an inventory, mark it as a requirement on a specific door, and play an unlock sound when the player has it, all written in chat. Because Summer is compatible with Godot 4, each key imports as a standard sprite or icon you can slot into an item system. This is a tight, focused set that clears the gate, and the art is largely free under CC0-style licensing for commercial use, with any attribution requirement shown on the asset.
