I'm not sure if anyone has posted this yet, but after recently upgrading to a current build (I had not upgraded in months) I have noticed that the buttons to start Bubbles game have been changed.
The screen still displays the instructions for the old buttons (power to start, A to exit) but the effect of these buttons have been reversed now. Power now exits, A starts the game. I guess this has been to make the buttons match most of the other plugins, in which case the pre-game instructions need updating?
