The white/blue girl only shows up if you hang around for ~45 turns and shows up on the left side. She's designed to be brutal but not infallible. I'm surprised people aren't complaining more about the ram-girl, she's kind of bullshit in v0.3.1.
Good to get a comment like this, though, it's the sort of feedback I'm most interested in right now since it's sorta experimental. It's a balance between "In the final game players will learn how to deal with early enemies while sometimes rarely tripping up, and blitz through the early levels to get to later content" and actually giving the player info to work off of. I definitely want to make where enemies have attacked clearer, maybe have a middle-mouse-button mode that shows all the moves the enemies just took (with paths to show it) and make it more obvious when enemies are readying attacks with an effect or aura or something, or when an enemy has aggro on you, stuff like that.
Edit: Just remembered, players should have access to use enemy abilities in the future which should help to understand them a lot.
