Hey, glad you liked the demo! I recommend replaying it once the next update comes this month, almost all of the overworld areas have been revamped and some new mechanics have been introduced.
As for your question; You need to recruit Tami as well (the Bank NPC) and she'll open the daycare. I'll make this more clear through dialogue in the next update as well. Did you recruit Benny? If so, then yep that's the end of this demo.
