Is the only categories here with friends? is it possible to do it solo at all?

Hello, sorry for the late response hope you don't mind. To answer your question: No, it is not possible to run the game without 2 or more players. Although there is 1 way, if you have 3 machines that can run Lombardi's World all at the same time, you can take control of all 3 characters and run the "Multiple Computer Mark" 1 player any%. Of course you'd need 3 computers and if you were planning on submitting the run you'd need to record all perspectives. There are no current runners for this category. It may be possible with only 2 pc's but it would prove difficult as you don't have much time to finish the maze whilst controlling 2 characters. Hope this helps!
