Hey there! I'm still at the early stages of development so please do it like you've been doing for now. Especially since this build's content starts before the events of the first one anyway.
So for this demo I recommend uninstalling the old one. Sorry for the inconvenience! I'm sure I'll figure out a more convenient way once we get more content and the updates don't alternate the code so much. It's still a learning process to me too :)
