i love the new XP orbs sound. I have pretty much visited everything new on minecraft and i want to talk about the awesome (and extremely hard to find) nether forteresses!
actually, it' just awesome because it's new... I like the way it looks, the rooms inside, i like the flowing magma falling from the roof room and the staircase with nether warts. i like the way magma cubes jump (they can't move forward with a block over them, i found one stuck o a nether forteress). The first time I heard the blaze sound, it spooked me out. Really, i spoiled the game using creative mode to discover pretty much everything.
but i'm not regretting it! i don't like the ender... too dark. I had some fun putting water all over the ender, then got bored and killed the enderdragon. took the egg and ran away form the ender. I started placing eggs randomly to see the way they teleport (once they're in your inventory, you can multiply it in creative).
