April Main Event:
1) Speak to the old man at the entrance on the beach and beat him in rock paper scissors 10 times
2) take the blank card you got from him to the man in red behind the receptionist desk
3) go southeast until you get to an area with a security guard top left, speak to the woman sitting down next to the corridor
4) first answer is down, all others are up
5) Go through the door to her left and interact with the painting, completing the operation.
I will post the ways to get to the 4 secret scenes if someone asks here.
