We have received several reports that realMyst for iOS is crashing upon launch of the game and in testing, we found that the game is not actually crashing.
What's happening is the intro movie sequence is not playing! This results in what appears to be a black screen.
This behavior is being seen only on iPhone and iPad devices with iOS 13+.
Until this issue is fixed, the possible workarounds are to either wait approximately 2 minutes, then tap the screen and you should be transported into the game; Wait a full 5 minutes, and you should see the black screen resolve into the game proper (after the time the video would be playing during has elapsed), or to seek a refund from Apple in lieu of waiting for a fix or using a workaround.
