The game gives you the delusion of choices.
When you accidently talk to someone, it's a route craving for your childhood friend.
I can actually get the Happy Ending where the Protag confess to her at the Beach despite talking to everyone (again):
-First thing you do is to pick up the girl, don't leave her.
-Go anywhere, go to the Beach, Cafe' or play games to increase hearts (for some reason, i don't even need that)
-Work at nearly 6 PM, till almost sleep-sleep time and end the day.
(Or you can speedrun by pick her up and take a 22 hours nap, fuck the kids camping day)
-Use money to raise stats, we'll use them to crush the xeno.... i mean crystals.
-The brat's game is rigged so save NEAR him BEFORE starting the game. First card best card, the last one require using the 10 card first tho.
-Finally, enjoy happy ending with good music.
(the hoe will hang out to every mfs exist in the island without reason and turn into a slut eventually so i made her life a nightmare)
