Oh wow, this is so cleanly executed. Great game! Going in, I imagined something gruesome and depressing (also the title is "GRAVE" so...) but it had some warmth in it. I like the life-transferring mechanic a lot, too.
Maybe it had been even better if "life" had a lot brighter contrast to the environment? There's something poetic about life in the ruin like this.
Nonetheless, great entry. Nicely done!
