the imagry reminds me of a video game from the late 80's to mid 90's two actually one dealt with a bumbling knight the other was some space ace that would constantly turn in to a weak nerd
Just a tip: Since this is a Unity game instead of a Renpy game, I would recommend disabling rolling back the conversation with the mouse scroll wheel and also introducing dedicated save points. As it stands, it's pretty easy to save scum in order to get all success rolls.
