No it's just a waste of time

You figure that it must just be a simple dead end, to frustrate anyone who might think anything useful could be hidden if anything it could house a trap or worse you could run right into the hands of the Manotaur which would be a bad way to start off. In either case, you doubt that it would be worth looking and instead continue on down the left passageway as the only real way you'll win this game is to get to the centre as fast as you can.

You head left and follow the dark snaking corridors having to double check to be sure you don't miss any passages, but eventually, the hallways turn a corner and you finally met with another passageway that branches off. You can head left which the corridors seem to of changed to an interesting shade of red or carry straight on where the passageway changes its color scheme to blue
