Hi. A couple more little bugs I've encountered while playing this game:

Freeze on title screen

1. Click the mouse to start the game.
2. As soon as the game starts, press escape to quit.
3. Quickly click the mouse again while the title screen is fading in, before the fade-in completes and the ball starts bouncing around.

If you time it right then the game freezes instead of starting the game. If you don't get the bug on the first try keep trying. It usually happens to me after a few plays if I'm getting impatient.

Autocomplete message shows up late

Very minor issue, but sometimes the "press space to autocomplete" message shows up one round later than it should. This seems to happen when the last face down card is revealed by sending a face up card from the table to the top. The player must then make one more move before the "press space" message appears, even though all the cards are face up. It seems like the check happens after the player makes their move, but before the game turns over any cards that have been revealed.
