This is a fan made choose-your-adventure-style visual novel based on the webcomic by Sam Logan, found at samandfuzzy.com.
Routes range from 5 to 20 minutes to go through. There are a little over 20 endings.
The game is nearly 200mb due to the music files, so it might take quite awhile to load. A MUCH more stable local PC version is available here: https://www.dropbox.com/s/9cf1lpk2npvkcx5/SnF%20VN%201.0%20Windows.zip?dl=0
If you are getting a black screen the first time you run it, it might take a couple minutes to load. First is the black screen, then the menu button will pop up in the bottom right, then a minute or two later the title page should load.
Once you have it running and cached, it runs fine the next time you open it.
I've tested it on two computers. For me it works in Chrome and IE on Windows 7, and on Chrome and Edge in Windows 10.
