mega vocab/audio

Excellent learning tools but how can I make the wen zi/ characters more visible on mega audio. The print is too light also very small as tehy flash on the screen. I need my magnifying glass to see them clearly. It's makes learning and memorizing very difficult. Please help.

Ok. so I've discovered that even admin don't reply. No one from Rocket Chinese has a solution or comment about whether they can improve viewing? Or if they may consider upgrading the game to make visibility better? :?
