An actual map has not been posted nor given to anyone yet, no. The only available information is what you see in the phase post.
Knowledge of the game is not required, as I describe your environment when you go to perform actions. Knowing where certain things, like benches, are just allows you to skip that part of the description, basically.
And if you're confused, you can send me a PM choosing to do pretty much anything, within reason. Unless you're presented with a specific choice by me, it's mostly just up to you to explore and try to figure things out. If you present me with an illogical or impossible action, it will simply fail. And since you have unlimited actions per phase, the only thing to worry about is which areas you head to, which isn't a problem during this phase as you have limited choices.
Pretty much everything will open up next phase. This is just to ease people into things, lol. If you have any questions at all, PM me, and I'll be happy to answer them.
edit: Also, please refrain from sharing details of your choices here in the thread. For one thing, it would be a bad idea letting your enemies know what you're doing, and secondly I've noticed a bit of a flaw in that I cannot avoid having certain information in the PMs I send without a certain amount of detail. The flaw being that people could easily learn who's what role depending on the situations they find themselves in, should they share it publicly. As a penalty, sharing any such information will result in your role being publicly revealed, and keep in mind that there's no lynches; your choices are what matter, and having your role revealed makes you far more susceptible to death.
