Thank you for bringing this to our attention. With regards to the search term pan-gu, our inclusion of tone marks most definitely has an effect whether the game will show up or not, so that has now been remedied.

As for "land of", this is likely an issue we cannot fix. Words such as "the" and "of" are often automatically overlooked by search engines, meaning using "land of" is probably equivalent to searching the word "land" only. As the search engine is controlled by itch, this is an unfortunate loss we have to accept.
