I don't know if this is a glitch or I'm missing something but I can't press any of the options in the forth minigame. The wasd and arrow keys can select the options but no button I press on the mouse or the keyboard actually activates the options, anyone else?

Not a glitch.

Either click on the option you want or hit “enter”.

You can only choose to “Fight” or “Act”.  “Spare” does nothing.
