No need of personal videos and wasting time, a short introduction of the participant should be enough.
Most importantly until they give out the wrong answer, the game must not be over. If time is up, it should continue the next day of the program. Think it used to continue earlier, so this change isn’t appreciated and so the game isn’t that exciting any longer. Hardly look forward to see it now.
Please make the above changes to get back the quality of the program.
