How are you doing guys?
I'm submitting a candidate for room 57. It's called "Return to Cell 666".
It's the first time I'm participating in a community project, so let me know if I did something wrong.
It's also been almost 28 years since I made a map for DOOM 2, so I had to re-learn the craft.
Edit: I think 57 was already claimed by @stochastic. In that case, mine can go to slot 60.
