Petz4 (day only) - Petz5 (overwriting!)
P5 version will cycle through day/night. This will overwrite the original Nursery, so make sure you keep the original somewhere safe in case you want to use it again. I'm still working on getting the bugs out for the P4 night version, it should be available soon! The two .wav files will need to go in the "Petz4\Resource\Playscene Editor" folder in order for the sounds to work.
