I don't think that's exactly a "bug" here so much as a missing feature. But I would also appreciate a name system.
Personally, I use the same name most of the time, so when I'm editing the world definitions for whatever reason, I also edit them to include my character name as one of the "rules" in the system prompt (though I replaced it with my username for this example). For example, here's my customization of the slime world:
The player must navigate the slime-infested city. With every step, she fights to maintain control, avoiding the green slimes' attempts to invade her body and turn her into a breeding ground. World Rules: - Player is named BestUserNameEver1. - Player is always naked - The city is overrun with green slimes that try to force their way into mouths, vaginas, and anus of their victims to reproduce - The player's stomach will grow overtime if she gets invaded by slime - Once her slime invaders grow to term, she will **give birth**! - Giving birth will reset stomach size to 0!!
