Just recently read some stuff about this game that the developer removed this game out of the steam store and is developing Haunted Memories: The Return. If you wish to aquire the original game to speedrun this wich is still possible do the following steps:

Copy Paste this ''steam://rungameid/241640'' Into your web browser and steam should add and install this. If this does not work follow these steps

Step 1: Create a new shortcut on your desktop (right click, new > shortcut)

Step 2: Enter "steam://rungameid/[App Id (this one is 241640)]

Should look like "steam://rungameid/241640"

Step 3: Name it the game you want to play

Step 4: Launch the shortcut, steam will automatically download the game for you

Step 5: Have fun!
