Nice job! I would call this more of a visual novel or a choose your own adventure novel than an adventure game. But I love games with a good narrative.
I really enjoyed the animation and the music. You achieved such an eerie vibe! And I liked the story - my only complaint is that during the dialog parts it was difficult to differentiate which character was speaking. If you changed the text font, color, or alignment for the different speakers, that might help visually.
Also, only one of the characters was an option to pick when I played it. I think maybe you just haven't created the others yet, though?
I was also impressed at how lengthy a game you were able to create in the short time. Great work!
