I really enjoyed the count to 50 ending. I'm not super susceptible to hypnosis so the repetition was a little lost on me, as were some of the visual and audio effects. But I do think they were well done! The snaps were nice and resonant, the variety in the spiral designs was very cool. And I'm thankful for the options to turn individual effects off.
The writing here is intensely satisfying, and I have come back a few times to find a new ending when in the mood. Also the species specific language is a very nice touch, it really helps keep the immersion.
