Ekacpuc

You wake yourself up in a pitch black room...

Walls feel very close to you...

You start screaming for help...

No one hears you...

You start feeling your way around in the dark room...

Is this just a dream ?!

You find just one thing in the whole room...

A cupcake...

You are hesitant to eat it...

You wait 2 days...

Nobody is coming...

Starvation will kill you before anything else...

You eat the cupcake...the walls are moving (or am i growing...?!)...you see a light in the distance...you feel different...

Objective: Destroy all the skulls on each floor.

Follow the unwritten rules of this insane room...if you can survive...

Hint = z, x, c

PS: Will post more details later if the objective seems to obtuse (partially intended)...
