I used a lot of paint making this game, and if you’d like to have a look, the time is now!

The Case of the Serialized Killer Art Book is an 58-page digital art book, full of the CGs, backgrounds, and other art from the game. If you're looking for a way to donate to the game, this is a nice way to do that and get some juicy knowledge for your kindness!

You can find the Art Book in your local files:
1. Open the Steam client and find The Case of the Serialized Killer in your Library.
2. Right click on the game's name or icon, and choose "Manage" -> "Browse local files".
3. Find the The Case of the Serialized Killer Artbook zip file in the "SK122" folder.
