to anyone who doesn't know how to get one of the two endings here's how to do it!
Ending 1: You need to pick up all the items you can collect then click on the box. once you exit to box Ace will say "I think I'm starting to get everything now..." or something like that. Then you can click accuse on anyone you want and it will always be wrong. That's how you get ending one.
Ending 2: Now this is a bit more complicated than ending one... first you got to collect every collectable in the game. (DON'T CLICK ON THE BOX YET!!!) After ponder every character in the game. Then click on every clickable thing there is! (Even the bucket) Then Ace will say "I have enough evidence now..." or something like that. Then you click on the box. (DON'T ACCUSE ANYONE!) After click on the box with all the clues then exit the box, Ace will then say "I'm scared". After you will enter shadow mode. If you want you can walk around and read what Ace says but if you want ending 2 you have to follow this last step... Then you accuse (or ponder I don't remember :,) ) anyone you want. Ace will say "I don't know who's who anymore... this is all a sick April fools joke..." or something like that. There you go now you have ending two!
Facts: The fair cat who you play as is Ace who also is the one who killed queen... Also no you can't blame/accuse him... the game won't let you sadly...
I hope this helps!
