yeah finally got people want to sell the zelda!! RM 60!! put me on your list if you plan to sell it!!

haha, almost forgot about this video clip :

i missed some of the spiders and mask mission when he's adult now, should i continue or just move along? anything i missed?

do you mean you just time skipped to adult era? after a certain progress, you can freely change from one to another
I can't recall if there's a permanent missable stuff though

you mean can become kid again in certain progress? see walkthrough they teach that before zelda kidnapped you can finish up the mask and upgrade your wallet to giant wallet already. now done with first temple and just inside the ranch. Stupid fellow don't let me out. i dunno how to go out now lol

yes, after become adult, beat forest temple then go back to temple of time and put master sword back to its place iirc.
as for the ranch... ride epona and escape via fence.. use boost when near the fence so that epona can jump over it. can't remember if you need to be at certain spot or not...
