Payment due: One dream.
This ain't hacked RAM anymore. I've actually trimmed off several frames before the last traversed bridge (removing intentional delays), scattered the remaining delays across a few transitions, and granted a wish.
There are extra delays, including sitting tight for 20 frames positioning a spawn and a little more walking in the Valley of Death. For a fairy, I'm sure this is a reasonable trade-off. Now, I haven't checked how mean the follow-up spawns are going to be for the trap that follows, but look at that fairy!
