Thanks for the video! Sorry there were a few bugs left in your pre-release copy. The bug you showed with the plates sometimes not spawning has already been fixed. A retry feature has also been added to let you get back into the action right away. The whole team is proud that we have fixed every bug reported to us by our testers and reviewers before launch! Since the pre-release version we have made too many improvements to list here. A complete list of changes will be available on the Steam community page at launch.
