Infinity.

"Greetings Agent, we are glad you accepted this job. Welcome to the void, where it's just you, your thoughts and the rooms we have designed for you, what rooms you ask? Well, we have designed a number of meta-places that Will appear randomly in your way, your objetive: to Cross as many as you can the space-time chaos Will be your worst enemy here, since at first, the room generation process Will be slow, but not to worry, because It Will pick Up the pace, not only generating New spaces for you to Cross, but also deleting those you have already explored, or not... We have also placed some utility items which can be found in some rooms for you to use, these being sodas, make sure to grab as many as you can along your way. And lastly, please dont fall into the void, as It would disconnect the simulation. Good luck! And remember you are not getting a raise for this!"
