First off, I would like to say that I am enjoying this game. I have only played for a few minutes so far, but I'm already having fun!
That said, I wanted to point out that some scenes, such as the one with the jackal (Ending 13: "Seen the Light"), don't use the right body part terms for the character's species. I've only played as a bird so far, but sometimes the game mentions my character's "muzzle/snout/nose" and "'ears' falling backward." There is also a typo in that same ending where it is written "the poke of your tip against your belly brings back a hazy image of the world."
As I continued to play, I noticed that many parts in the game make that mistake.
Edit: I just finished playing, getting Ending 15 (as well as Iana's ending). This was an amazing game! Possibly one of the best text-based hypno games I've played! All the different ways you can get hypnotized, as well as hypnotizing the others, are very well written.
As a few have already mentioned, adding a "Good Ending" or even writing a variation to Ending 15 would be a great idea if you ever have the time and motivation to continue working on this.
