This is one of the hardest May Wolf VNs for me to review so far. It's really good but like Everyone is Asleep(and for similar reasons), I'm not sure how to put my thoughts on it into words. But I'm gonna try cause it deserves so much praise. Kali is a really compelling character, and the way he meets El in every world is so bittersweet. So much of what happens to the two of them is senseless and tragic and yet they still make meaning out of it all. The conversation about movies really strikes a chord when you look back on it after learning more about Kali. The concept is wonderful for exploring grief and humanity. It raises the question of what makes you you in a way that I will be thinking about for ages. The art style is simple and charming and serves to establish this well, especially given it's slightly different in every world.
However, I don't believe it fit the theme very well. I assume Kali is named after the Hindu goddess, but I'm not sure how that connects to the plot at all, and it's not really explicated anywhere. El having the names of biblical angels is more clear, but it doesn't do that much to build a folkloric theme. The advice Kali's mother gave him could also be folklore but it seems more like a mnemonic to remember important advice than stories. The story the first El tells Kali is also folklore and that's interesting, but there's so much disparate elements/folkloric references that it didn't feel like any one was particularly important.
But I really enjoyed this one and it definitely gets a high rating overall.
