I managed to reproduce this same bug, although I'm not sure what I did to cause the issue. Essentially an alarm would go off, and then upon snoozing it, the time would reset to 7:59. I refreshed and the issue went away.

Watching your VOD, I was able to figure out what the problem was. From what I can tell, the issue appears to occur when you click on the game, particularly on the web build. I've published a fix that should prevent the issue. Thank you for playing my game and (accidentally) helping me fix some bugs.
