There was a part I wanted to add to the puzzle solving, but my free video editors would let me do video overlays ;-;
pretty much it was on HOW to get a row done, so you could easily follow my chart on beating slide puzzles.
[] = empty slot
pretty much to do a row (or column) you prepare it like this:
desired result:
ABCDE
? ? ? ? []
Start:
? ? ? ? ?
? ? ? ?[ ]
First line up like this:
?ABCD
? ? ? ?[ ]
Get the last piece of row
under/next to desired slot:
?ABCD
? ? ?[]E
Then get the empty space to the
where the
? was:
[]ABCD
? ? ? ? E
Shift ABCD into their proper places~
ABCD[]
? ? ? ? E
Shift E into its place :3
ABCDE
? ? ? ?[]
Done!

(you can look at this in a mirror (or something like that) to if you need help with columns)
