Finished the game. And, I agree with nalurose, the story seems difficult to understand. I notice its in the "playing God" category of another contest, so I doubt I'll be spoiling anything related to that concept. I just feel like there needed to be a little more text describing the bad ending; or pictures. It seems your guide only benefits from the good ending; at least, that's what I semi-figured out. I wanted to try to get the hinted at "3rd Gate". But, alas, I wanted the good ending. Also, it doesn't seem like the choice at the very end has any real meaning. There's no "New Game+" that I'm aware to take advantage on your decision to the final choice. However; the Good Ending final pictures did help to answer a lot of questions though not all of them, which is still quite intriguing.
If this game does get picked, I am curious as to how it will be fleshed out into a full game for the IGMC 2018 contest. I'll leave my actual review on the download page.
