Okie i just finish page-to-page to my previews ...
i saw a lot of Theory on what or who is this Mystery person that MC saw at the park and Old Man look alike MC ..
okie this is my own theory if Dev is going to make it like the Movie "PREDESTINATION with a twist of BACK-TO-THE-FUTURE and CUBE"
1st is the predestination
if MC is the Old man that was traveled in time and gone to the past till present just make him self old or it was bacon who went to the past and stayed there and see MC and himself to see the time flow and another mystery guy who was in the park when MC see her childhood friend half naked..
what im saying is in this game so good that it comes to make excite where you wondered why did it happen?
in Predestination movie if you haven't saw this movie i recommend you to see it, it is really nice Sci-fi it involves in just 1 persons life i mean their where two time traveler the 1 who give him the case and etc. and him what change is it doesn't involve wither he changes it or not cause time will always flow in its way or to say looping. in the game i think its only 3/10 in its story for now if im not wrong MC has a best friend whose father was an inventor of his time-Machine and now his friend already traveled through time and changing the TIME paradox and rewriting everything and now there is a time jump(which is u where traveled in time but their is a side-effect which is your alter-selftime is syncronizing with you and thats why MC got time jump where he was about to sneak up to his parents room and her mother got confuse why her son acting strange) so its just that MC's got time jump was only his unconscious self mind in short his soul or what ever i called was transferred to that body which is like switching body or soul were they had no idea.
in the movie CUBE 2 there was involve parallel world which is like the movie "Triangle" where their are possible scenario where you make a choice and that choice creates chain of possibility which is in the game where we all know wither old man or the mystery guy is another parallel world time-line which is the twist or maybe the MC is the father of bacon but in another parallel world which is MC is genius and got stuck in that world the reason why he build that time machine to find where it got wrong or why he is stuck in that dimension or maybe the reason old man has the time machine bcuz he is bacon who got stuck in the past and now he is going to stop bacon to go to past so that he will never experience what he experience for.
so to summery this its like this
