Thanks a lot for your message Goobie :^)
You definitely had the good ending, there is only one. The other is a humorous bonus which requires a very specific action revealed at the very end of the game provided you have a score of 35/35.
You'll find this weird but the scene you're talking about is also a variation of a nightmare I had when I was younger and I also discovered that 2 of my friends had already had the same one. It must be part of the list of common dreams, like flying or failing to run.
The enigma you're telling me about is vicious and afterwards, we wonder how we managed not to see it ^^
I'm glad you're appreciated! Come back here whenever you want, you are welcome. Greetings from France !
