Hi! Thank you so much. There are two endings, one has conditions and is “secret” and the other is what happens if you don’t meet those conditions. Unfortunately, we ran out of time to make the “secret ending” not indicate that the other ending is secret (the message appears for both endings haha). If you saw all the flashback scenes, you got the “secret ending”. If so, try again while skipping one or more flashback scenes and you’ll see the alternate ending.
Again, thank you.
