This is an amazingly new twist to an old classic. It's easy to learn, but difficult overall. The music fit, the map was nice, the controls fit well into the game. The enemies are balanced in speed so that they can be escaped if you play carefully. The map spinning was a bit odd, but knowing which enemies to avoid and which ones are safe would be an improvement. The gameplay is short enough that in as little as 5 minutes (and ten seconds) I could complete a round, or I could play for hours since the enemy movement is almost never predictable, and therefore the game has nice replayability.
As you have been made aware through the comments, the creatures add an unusually steep slowdown if even one touches your ball at the wrong angle. Often, when on straightaways, the creatures on your ball will make you virtually stuck in place while trying to escape the fastest ones.
It's a difficult, yet new concept, and I feel it was done well.
