So I got it running, just downloaded the whole thing, opened it up in notepad and saw it was a html document and just renamed the file. You can make it run straight in the browser from itch by creating a zip file containing the html document like this:
Zip file | - index.html
Yes it has to be named exactly index.html (or Index.html I can't recall) otherwise itch yells at you.
WHOA I was not expecting that ending! That was so cool! I'd loved to know a bit more about the fate of the spirit and how it got it's ending. The choices in the end were super interesting. I don't know if you have written "correct" answers, but it was really fun nontheless to guess. Even though it had no impact on gameplay it was still super interesting, because you actually had to think about what the spirit had around the house. The images are also so damn adorbs I can barely handle it. The plant and dustbunnies were amazing. Fantastic work!!
