The description doesn't show on this page. I'll copy-paste it here if you don't mind: In this game, you find yourself in a sprawling labyrinth, and you must find keys and defeat enemies to escape within the time limit. The map is huge and complicated, so it's recommended that you take some time to explore and make a simplified map for yourself.
@Ceramique Thank you! :) It's not intended to be beaten on the first try, you're supposed to explore and deduce the fastest route. :P
@Ariomaru Thank you! :) When first starting the game, I had set the time limit as 5 minutes. But when it got to the point where I realized I needed to increase the time, it was too late to make it smaller. :P
