For you who experienced a verification issue on How to Sing to Open Your Heart, I barely noticed there is a new website rule that has been added recently, so I need to fix the verification link within the game file. The patch is fixed the issue, so you should be able to play the game now.

Although, for Mac users, please launch the game through the itch io client, as the fix might cause the game to stop working outside the itch io client (because of Mac security rule)

Please contact support@roseverte.net if you get further issue.
