The idea of the game was very unique and the graphics were stunning!
I had three main issues with the game though.
The biggest one is the lag. I don't think this game was optimized well because it felt like I was getting about 20 fps while playing.
Another issue I had is that I didn't know what to do until I read the itch page. That's something I don't really like in games. I think there should've been an interactive in-game tutorial to alleviate this issue.
And my final issue is that there was no music or ambiance. Though I absolutely understand this since 7 days is only so much time.
Overall, an excellent idea with a stunning art style that was, in my opinion, soured by a lack of guidance and lag. Though if this sort of concept was expanded upon (like the players dialogue telling stories about them and their actual lives or something), I could absolutely see it working as a full Steam game!
