I had this tab open for about two hours, because the screenshots intrigued me so much and I didn't want to forget to play this game. And god, did it deliver.
The atmosphere is just unbelievably good, especially for a game jam. The way you used the assets was amazing. Never really did my immersion break or did the journey feel tedious or boring, it was engaging 'til the end. This is one of the games where I barely run, just so I can deliberately take the game slowly and take in the world.
And the end was overwhelmingly emotional. I can say without exaggerating that it nearly brought me to tears. While it was obvious that your "Guardian Spirit" was more than just some magical butterfly, the delivery at the end of the game really made me feel melancholic. I didn't even want to switch out of the last screen to write this comment, because I didn't want to stop the music.
I added this to my collection. I want to play this again at some point when I actually have the time to properly experience it. Until then, keep up the good work.
