I really like the fact that Notch has rised the cloud layer up to the highest level of the sky. No more clouds floating through our towers and mountaintop homes.
Still a few bugs to be found. I've had immovable wood blocks appear on my floor and in my inventory, as well as a few game crashes. but thats to be expected. Its actually amazing how relatively bug free its been.
Can't wait til the server is updated with the official version. Its amazing how lonely singleplayer feels after you've played with friends.
*Edit: Hehheh. Just discovered that with a fully charged bow, you can one-hit kill a Ghast. Be vewy, vewy quiet...
