I think I am stuck. Maybe I am missing something, but I have tried everything I can find to get out of where I am. It looks like I need a blue key, which I do not have. Attempting to add a jpg of the map where I am stuck.
See this section of the map. I climbed the vine in the room on the botton of the picture and it came out in the room i am in now (See arrow). I then jumped up and on to the next level.
