Thanks man ! And sorry for the loss of time, in the jam version I've forget to link the button to the door so you can't open the door x) anyway I'll post the post jam version tomorrow ( or a little bit later ) and if you like the jam version you'll probably appreciate the adds of this new version !
Is there any way to restart the game so I can try the new version from the beginning? :)
I've reupload a new version of the post jam where I change the save file name ( and other minor fix ), so I think than if you download now the post jam version you'll start with a new game, if it's Idoes not solve the problem you can always go on %localappdata% and find a folder named "The_Vast_World" ( or fairy song, not sure) and delete the file in, have fun !
