Nice idea!
I just searched for "Green Five" and wanted to find this title:
http://hol.abime.net/5382
but I had no luck, no search result. Also with
Green
& Five
i only got all "five" and "green" results.
Do you have any search tips for phrases with more than one word?
Anyway, i think it's a great idea to have an Amiga related search. Nice work!
You should add
http://obligement.free.fr/articles/listejeuxamiga.php too, this site has a lot of hard to find games listed.
