Thank you for your kind comments, and thanks for the suggestions!
I'm a bit surprised at #1 - that was a HUGE oversight on my part and should have been done.

#2 as well would be easy enough. I seemed to have gotten hung up on the idea that people would want to play for the fastest times. In retrospect it was a bad idea because you aren't competing against anyone, so setting it up so you could get the fastest times wasn't necessary.
As for #3, you can create your own custom graphics, use you own fonts, and sounds. I should put some documentation together on how this is done. It is rather simple, but might seem a little tricky for those who aren't used to it.
Thanks again, and I'll see what I can do.
