Some strategies:
If you go south at the beginning, you will encounter jump scares.
In the hotel, there is a plot of drinking Coke. Whether you agree or not will not affect the main storyline.
Eating in the restaurant will increase the size. This is the same as Coke and Slime, but there will be BAD END special dialogue when you are full.
In room 205, you can find an angel to upgrade.
Go to the factory on the right to learn the mission, and then go to the factory warehouse to fight. Then talk to the factory manager and complete the mission.
After resting, talk to the NPC on the right side of the factory and go to the mine. After getting iron ore in the mine, go back to the factory to sell it and forge a pistol. Go north in the middle of the mine to get the key (but it seems useless now). Choose a route at the crossroads (there is a prompt, remember to start south and end south.)
Get the mission item and end the beta.
A little off-topic:
This heroine is very similar to the supporting actress "Wendy" in a game I made (called Diwen when masked, which is the directional reading of Wendy). She is a blonde, green-eyed woman wearing a red windbreaker and a red hat. They are both windbreaker women who like to use revolvers...YES~yes~
I also made her "doll"...
