Didn't finish my round but I was even thru 11 before I got tired of it. Apart from the annoying music, the only other thing I didn't like was the blind shots you had to play on most holes. Not being able to see where the hole is prevents OD from making eagles. It's difficult to find the proper angles and it's of course all about angles.
Can't seem to find if there's a thread on the old mini golf. It took me about 300 games and about 1500 curses, but I aced every hole for a perfect 18. Haven't played it since. I'm not a big fan of the new one though.
