The king has tasked you to find the lost ruby, but he clearly doesn't trust you, as he has given you a poison. You must find the ruby and return it to him within 650 minutes and he will administer the antidote to the poison. If you fail to achieve your mission within 650 minutes, you will die. Mind you, there's a good chance that you will get killed by one of the other denizens of this strange land long before that.
Notes
This game was recovered from the author's archives and placed on his web site, which is now defunct. The game appears to be a work-in-progress, as it is very buggy and is missing a line of data that makes it impossible to finish the game. See the solution for the missing line or download the bug-fixed version, which corrects some other bugs and spelling errors.
