Keycards is a system that people can use for challenges, points in other games using backend systems in scratch or other things. You can only use your keycard if you have one and you can NOT use others keycards as people who use others keycards will be banned (in the project). =================How to use================ 1. If you are lucky, you will get a code. 2. If you get a code, enter it in the system. 3. Your keycard is one-time use so you need a new one if you want to use it multiple times. 4. Only games made by me can get rewards using keycards. If you want rewards in other games, I will try to ask the developer of that game if they can implement it. 5. Any rewards you get in other games would take a while to be added. 6. This only works for scratch games so don't get too excited heheh.
