I'm having issue with Puzzle number 250! which is the last of the normal boards. Although upon beating it if IIRC 5 bonus stages appear. It's been a long time (13 yrs.) since I beat this jazz. I need a little help so I can get this monkey off my back. And I'm so close . . . Assuming few have seen the boards later on here are some codes to get there.
Warning, these levels are quite challenging - they are not for the weak of Heart or Mind.
247: Horse
248: Balsa
249: Noise
250: Micky
Reserved for Screen shot later
I can't seem to get all the boxes out of that top right area of the board where they start with the 1 hole in the wall to the right.
