Subject: Andrew's list of quirky features

 

One notable omission from Andrew Broad's List of Quirky Features is the example of Willy walking through an Earth cell located above his head as per the second diagram at this link:

(At least, I don't think it's on Andrew's list?)

[I hope that comes across okay when you view it here.]


I would just like to add that the reason the above doesn't qualify as an ILB (and why Andrew qualified his comment by saying it's merely "a bit like an ILB"), is because by the time Willy has passed through the block to the point where his head is horizontally aligned with it, he is no longer jumping, but falling.  This means that the subroutine at #9EBC doesn't get called, and the consequences of that are twofold:


(1) He won't get pushed down through a solid platform situated two rows below the block; and

(2) He won't be able to fall to a depth of more than two cell-rows below the starting point of his jump without being killed.


(N.B. The other thing that the 'ILB code' at #9EBC does is reset Willy's Movement Flag, to terminate his sideways motion - which can be applied to useful effect on the Conveyor in Tree Root, etc - but that wouldn't be applicable here, as Willy will already have stopped moving sideways by the time he has fallen through the block highlighted above.)
