Everything about the game looks great! You and your team have done a great job. Unfortunately when I play the game on Mac, entering both Classic or Modern mode doesn't seem to load any visuals other than flashing/scrolling unreadable text.
(When paused/showing high score) 
The gameplay and audio still seem to function while this happens, and the menus before this work fine, so I'm not entirely sure what the cause is. Any chance of there being a fix?
