Oh, this was a lovely game! I'll admit the game completely fooled me, and I failed to see the bigger allegory (which I should have considering the dates). And it made it all the more heartbreaking: more than a man looking for the love of his life, I see the protagonist as the mourning of a whole country for the part of its citizens who disappeared during those disasters. This is a very powerful game, and the metaphor was truly perfect.
Also, I really loved the art! The CG was absolutely GORGEOUS (especially since you tackled what I call the "cursed angle", because I've noticed most artists fail to draw in this angle, but you really didan amazing job), with the right amount of melancholy and nostalgy. The BG of the CG was very beautiful too! I also appreciated the slight alterations of the Ren'Py default GUI: somehow, your changes make it look a bit more retro (in a good way), accompanying the theme of memory. And for the music track, well, I used it in a recent game of mine, so I agree, it's a banger, and the right amount of love and yet melancholy - it really fitted the game!
Congrats on making it!
