First, close the game. Go into your local appdata and look for the game's file. It may either be labelled "Polymute" or "Transmute_Deluxe2". When you find it, open it up and go into the "Options.ini" file. Look for the setting labelled "Respawn."
Once you find it, set the x value to 2464 and the y value to 1176. Save and close the file, and then run the game. You should then be back outside the spire.
