1.2 is riddled with bugs, inconsistencies and passability errors. I'm currently going through the game and trying to root out every major one.
Notably, 1.2 IS ONLY PLAYABLE UP UNTIL THE END OF THE HOTEL MEETING IF YOU DO NOT BACKTRACK TO THE ALLEYS. There is a messed up teleport. A fix for this is to hold down Ctrl while test playing- other than that it breaks the game. I am so sorry I did not get to this sooner- hopefully the full completed version will be up real soon!
