Song of Memories is not longer going to release in 2018. Publisher PQube has taken to Twitter to announce the delay, and share some information on what happened.
We are very sorry to announce that Song of Memories will be delayed to 2019. While we had hoped to bring you the game this year, we have seen unexpected development issues that are not related in any way to the platform holders. We are doing our best to bring you the game as early as possible and we will communicate a release date in the new year.
When a more-specific release date for Song of Memories is shared, we'll be sure to bring it to you.
