Colourful backpacks in the store
The store in the game now sells backpacks. Yellow, purple, grey, golden and orange backpacks cost 20 coins each, and twelve new designs cost 50: dragon, demon, crown, heart, moon, crystal, buggy, mushroom, energetic, lilypad, minotaur and wolf.
Every one holds 20 items and weighs 18.00 oz, just like a plain backpack, so it changes how your backpack looks, not what it holds. It goes straight into your inventory, and from then on it is an ordinary backpack: you can trade it, give it away, or lose it when you die.
