Mini Pack : Keys v1.0
Keys are important to folks on an adventure. Doors, chests, panels - they're all locked! This pack includes a good selection of keys from every day keys to special fancy keys.
Every key is also rendered out as a sprite so you can include it in your HUD or Inventory system.
What Is A Mini Pack?
A small, affordable collection of professionally crafted assets that you can add to your Unity project. These packs are meant to save your artists from having to build every little detail in a scene. Use their time for something more valuable- like iconic vistas or hero props.
Even if these are not exactly what you need, maybe they're far enough along that your artists can tweak them a little to get what you need.
