There is a music player that you can buy at the shop (5000 rep). This will let you listen to any song of a character you have completed the base scene of. It will simply become the song that plays in your tent any time you enter. ^^

I deleted the previous comment to avoid confusion, as my assumption may have been wrong as to the cause of the issue. Upon experimenting, I believe I may have actually found the problem. It may be a resolution issue, actually. If you toggle off Full Screen (or vice versa) can you see the buttons?
It seems very specific resolutions can cause the planes to go funky. (This can also happen if your browser is zoomed/unzoomed)
*If this is the case, I will look to have it fixed up by next version*
