I liked the art assets, you do a great job of presenting a very cold, scary, rapidly changing climate. With the lonely houses and such. I also love the piano, and I think it was an extremely interesting decision to make the piano a spatial sound with the source being the fountain.
I like the dialogue but a little clarity about objectives and plot would have been nice. For example I have no idea why the doors close on that first house. I'm also unsure about old man Wells interaction on the southeast house.
Overall I really like the plot, with the caveat that I think the anti-climax at the end is kind of counter to the dire rapidly changing environments, the desolate feel, the anxieties of the characters and their desperation to preserve the resources necessary for life. I think something a little more bittersweet might have felt more impactful and salient considering we all are experiencing similar anxieties in our world - with no attempts at solutions in sight. I also think it might be more suited with the loop mechanic.
I think its a thoughtful work, great release.
