If you have found a bug please leave it here. If possible screenshots and even better, videos can help me squash the bugs. 

It's come to my attention that the second puzzle immediately times out and all subsequent puzzles do the same. I have not encountered this issue whatsoever on 3 different windows machines. I believe it could be a zipping error or a MAC error. But I'm not sure what could be causing this bug as the eventing sequence doesn't have an error with stopping the timer right when the puzzle starts.
