I really enjoy the pause feature in your games but this feature doesn't seem to be available in the Little Exam.
Trying to pause a game of Uno between rounds worked but I had to press shift+p again to resume the game instead of just being able to press enter.
The last thing I wanted to bring to your attention is the fact that when I have the option set to give me a confirmation before exiting the playroom and I activate the "leave the playroom" option, the program just hangs until I kill the process manually either through the task manager or the "end program" dialog that eventually pops up.
The program does not hang if I don't have the confirmation set to display.
I hope you can get around to fixing these concerns soon.

For your first question: the shortcut has changed, it's now effectively Shift+P both for pausing and resuming. I'm also aware for the little exam, it will be fixed soon.

For the other bug, I'm afraid that more info is needed.

The reason for the confusion is when you press shift p to pause a game it will tell you to press enter to resume the game instead of shift p to resume the game and that is the error.
