Thanks! I'm hoping that I can fix the key input issue soon. I used the automatic key repeat from Windows, which has a longer first delay, instead of checking the key state on a fixed interval, which is what I should have done. The signs on the floor were initially just as a stand-in for a narrator, but I thought it looked neat to have something other than just the character and the floor tiles reflecting, too. The part where all directions appear to say "Don't go this way" due to reflections was a happy accident, haha. :D
