I cant, I have only one saved file, and it is stuck in the botanical center :(
Aaaaaaw! That is a beginner player mistake, save often AND ALWAYS keep several saves in case you need to reload a previous save!
Now if you are stuck in the botanical center and you can't get out of it then you are screwed unless the developer takes on him to fix the issue quickly so you don't have to go back to the beginning of the game and repeat everything.
