OK, after playing the game much more extensively this weekend and getting to play multiplayer with a friend, I have gone from enjoying the game to loving it and my previous gripes have been pretty much allayed quite a bit. Even though the levels technically keep repeating, the random-ness of it all keeps every play session fresh and fun pushing you to try new tricks and techniques in a subtle and intuitive way.
Also, getting 4,000 yds in marathon mode is a rush. I finally got over 300 points in score mode which is in no way easy. Earned every one 'o them 362 points with a lotta sweat in between Halo 2 sessions with my brother and friends. Now I just need to dig into time attack and challenge a little more which are interesting so far. Seems like the cactuses are much worse in time attack. Also, on multiplayer I am constantly amazed at the DS's wireless capibilities, being able to send a game through walls to a friend in another room is darn neat. Too bad he kicked my butt both at Halo and Yoshi. :(
