Hey @DrGamer! The pickaxe is in the room below the the bird puzzle room, so you won't need it to get to the south entrance. If you've rained in all the buckets, the very last platform on the lower left will have a bridge extending to the right, which you will use to get to the door to the pickaxe room. If the bucket is down but there is no bridge, try walking out anyway. Sometimes the animators on game objects don't behave correctly. If the bucket is down, there is no bridge and you can't walk across it at all, try leaving the room to the north and coming back in. If that doesn't help, you've run into a bug and we will look into solving it ASAP, but you will have to start a new save to progress.
