It's a good game, but only when you're actually able to play it. It seems that either the servers are down, or they're so full that within half a second of emptying a world, it's full again and you're not able to get in.
I'm glad you added two extra servers, but it's still not enough.
It's too simple to be any good for long. It would be a good idea to add power-ups (a buddy to help you, bigger pac-mac to collect more pellets, etc.) and levels (you need to collect a certain amount of pellets to advance in the time frame given).
