Hey MousawiDev! Thanks a lot for the report, we've seen this happening very rarely, couldn't reproduce it during development. I think there's some kind of bug when the transition to another stage is happening and the player is pressing something. I think we can't make any changes on the game now, but if the screen goes black that's for sure a crash, unfortunately. Sorry for this, as soon as GTMK video is out we're going to fix this.
