[SysTaMatIcS]

I got this game in 2004 , and beleive it or not , i reached more than 90% of it , but i cant finish it , i reached the place where i must stick the dagger in the thing with the sands in it , and when i jump somethin weird happens , and i find myself with the princess in a dark place and then she says that when she used to be a kid her mom told her abt a word if she says it a magic door will be opened , and indeed the magic door opens when she says the word , and suddenly she disappears , and i find myself running in a long hall , so i keep running and hear her voice calling me , till i reach this little pool with doors around it , but nothing leads anywhere , can anyone help me??!
