The bird isn't in the window in 1981. I can see him beyond the window but I can't get him to come to the window with the flower. I must have done something wrong but I'm not sure what.
Only frustrating thing was that one step required me to enter a room, solve a puzzle, leave the room, and re-enter it again ONLY after a certain period of time had passed before I could continue. Before taking that last step I couldn't proceed even though I knew what I had to do...
Game freezes on level one of the body world when I reach the end of the level. Just sits there and loops audio with no change in visuals... Game looks good but there are clearly some bugs that need addressing.
