Not sure if it's already been reported! But my character will attack the doll whenever I try to navigate the menu with the up/down keys on the keyboard.

Not entirely sure if she can die in this version, but it's still enough to give me a startle!

P.S: I adore the plot twist in the end.

I had assumed somebody had already reported it, but it doesn't seem like any update has addressed it yet.  You can't seem to kill the Doll (though she does spray out white blood), but you can end up wasting bullets from your gun if you have one equipped while in the level-up screen.
