I want to be able to fly on survival. Is there any way? I want to be clear about this, though; I am not interested in cheating or griefing in MP, this is for playing solo survival on peaceful for construction only. I'm already using an inventory editor to make my deaths less... Aggravating.
Now, I want to play survival, otherwise I'd just use the <sensor> client with classic. Before you ask, yes, I have bought the game quite a long time ago. The reasons why I want to construct things in survival are many more blocks, shades, running water etc. I'm pretty sick of falling down and dying (even when holding shift, sometimes you slip) when I try to make my high towers and rope bridges.
After searching for a long time and what I've found so far... Shady sites, viruses, and so forth, made me realize I would probably be better off just asking here.
