 Stuff to do before release:

 - Make grass grow slower; utilize timestamp difference

+Stuff to do after release:
+---------------------------
+- Make sure server handles removing grass when a block is placed (etc)
+    - The client should not do it by itself
+- Block cube placement around player's head
 - Protocol version field
 - Consider getting some textures from cisoun's texture pack
 	- Ask from Cisoun
 - Make sure the fence implementation and data format is good

 	example
