When I got to day 20 and when I unlocked the rooms at the top (I think kitchen, water, gift shop and tours)

I checked the balance, and by around days 20–25, the player should have accumulated enough resources to unlock the automation upgrades—Tour Auto-Start, Kitchen Auto-Serve, Souvenir Auto-Craft, and Bath Auto-Fill. From that point on, these tasks should be handled automatically and stop demanding the player’s attention.
I’ll keep in mind that automation needs to be unlocked a little earlier. Later on, the player also gains the ability to explore new maps, although they currently don’t contain any new mechanics—only higher-quality varieties of wood and stone, which speed up resource gathering and overall progression.
