I think you missed the 9th possible sequence, in which Hikari does meet an untimely (if convoluted) death:

For that to happen, these steps must happen:
* Hikari jumps over the block that's currently directly in front of him
* You then jump when you next have a real choice to make
* Hikari then bumps into your head (which he would be silly to do, since jumping will take him to freedom immediately)
As for the minimum typing you need to do to ensure survival, I think you can get away with typing the 3 commands, "
xxJ"
, right now, where the x's don't matter, since your next 2 moves (bumping into the dead end, and jumping backwards) are forced anyway. Am I counting the same way as you? If so, what were the 4 moves you thought you needed?
