The tour of the lab is all well and good but it gives very little information on how to actually play. The visual ques the game gives when having sex doesn't mean much if you don't understand what any of it means.

I think anything very in-depth should probably wait til later though, as if you made a detailed tutorial this early on, it'd become inaccurate whenever something is changed.
