No. I'm not bothering with some so insignificant as the restart game button. If you need to reset the game I'm sure you can wait the "grueling" 15 seconds. It would take me weeks to get everything re-done and re-tested again.

Anyways, I hate it when people restart the game constantly or randomly. I like to check out the scores at the end of the game and get to chat for a few seconds before the next round. So removing it is a good thing.
