The reverse-engineering I did LIVE yesterday gave some fruits. :p

It works like this:
1. nybble8 is zero: Die if the ground it's on disappeared, fall to the left
2. nybble8 is non-zero number, but not 2: Die if the ground it's on disappeared, fall backwards
3. nybble8 is 2: If ground disappeared, keep falling downwards
