The music selections vary in length from a short sound to a 3 or 4 minute song. so if you heard anything...it was probably right...I need to add in some longer tunes or a handful of loops... lol
A back button...to title screen is a really good idea that will be in the next build probably. I have lots to do for the game, but may be taking a -few weeks- break from working on it. (ahhh...life)
The more you play it, the easier it becomes. Its not a game where you can rush things that's for sure. The best I've gotten was 23...and I don't think anyone else will make it that far.
