Before reading, I just want to say that my English level is somewhat basic, so I apologize for any possible typos or mistakes in this comment.
Honestly, the Halloween special was really good — I actually played it more than once to see all the different choices and interactions.
To start, the scenes were of very high quality (I didn’t expect Selene’s scene, but I really liked it).
Overall, it was very entertaining and had quite a long duration (around 1 to 2 hours more or less).
I only found one issue: during Lily’s scene, after choosing how we want to behave with her, the dialogue isn’t translated and switches directly to English. I’m not sure if the same happens with other languages, but it does happen if you play the game in Spanish.
Aside from that, I assume this is separate content, right?
I say that because I remember that in version 1.5.1 the MC ended up turning into an Anthro.
In short, I really liked it, and you added a lot of scenes that I didn’t expect.
thanks for the update Invisible Cactus :)
