I have an idea for World of Seals. Since World of Seals is a virtual world, people should be able to create rooms. Not only their rooms, but also other rooms using special items, layers, and items they can create and save.
Then in these rooms players can chat and play games like tag and hide and seek using a your it feature, where the person who's it tags someone,then the person they tag is it, or everyone, then they chose a knew player to be it.
To save space on servers, players will only be able to save a few rooms, and if they want, they can let rooms lead to other ones of theirs in whatever way they choose.
