Another Matrix fan here! The introduction is very cool, I really liked the beginning with the phone ringing. I took the red pill and got stuck on a balcony, I think it may be the same as the one AoQ comments on, I took a screenshot in case it helps!
Love to hear people getting the Matrix references!! Secret here is that you're in the right spot, just gotta stick your head one of these windows as they are portals too. Means you're at the VERY end of the puzzle. :) Thank you so much for playing!
