Yes, the game only has one ending! There's no escaping this ending...
This game was my first experience in creating games, so I basically tested many things in it (although the game is short in general) including the plot method, in the conception of the game I had already planned this ending (I always flirted a lot with dramatic and tense books)
I wanted to convey that feeling in this little game
Apologies if I somehow broke your expectations in a bad way...
I'm very happy that overall you enjoyed the experience :)
(Please, if you haven't already, play my other games XD)
Thank you very much for your comment!
