Stop hating on Jeb and Dinnerbone for adding sunflowers. You don't even have to use them. Nobody hated on Notch like this. I am certain if Notch was on minecraft, he would have added these things as well. As for the horses, they aren't that bad really. If you don't want any of that stuff in your game just switch back to an earlier update using the new launcher that Jeb made. You people have no excuse to hate now.
Now about this stupid thing.
Sunflowers: duuuuumb. Basically what rkpkid said above.
Impact Particles: barely Noticeable.
I think pigs are cool, too, but saddled ones are a waste of porkchops.
New Particles: How can you notice it!?
Anyway, please let the impact particles be toggleable.
I Hope so.
I assume the particles will be togglable along with the 'Particles' option in Video Settings. On the subject of Username changes, those are planned for an 'Account Update' at some point (if they are ever added, that is).
I never needed a way to determine directions because of Rei's Minimap, but I still think sunflowers will look amazing in the game! I don't see why people are complaining about what the developers are doing with Minecraft.
*Sigh* Survival Test, I'm going to miss you and all the old things. But what can I say, look at the 1950's style of music and than look at today's. Things have to change and become more advanced in order for us to move on. Still, I am really going to miss The old Minecraft
