I completely missed the other three endings until I watched Chirin 06's Video, which I swear is not mine!
I didn't realise there was an inventory!! So, of course I just got the simple ending. I'm glad there was so much more content because I noticed the hints!
I love the game, and it was close but I'll say...
!Spoiler!
Mr.Chicken disappointed more than what was in the safe ;P (Also, what was with the screen effect when you get the coin?)
!Spoiler!
Thanks for the great game!
