The author says the following on the Doom World page

Excited to finally release this tribute map. Last August I lost a good childhood friend of mine and took it pretty hard. When I was visiting my hometown for his funeral, I connected with his parents who shared with me some of his old belongings. Among them was a copy of an old map of his backed up on a 3.5” floppy from high school. Thomas and I were into amateur Doom mapping in the early 00s but I had never seen this map of his prior to uncovering it on one of the old floppy discs. As a way of paying tribute to him and all the great memories we had together, I took the plunge and installed Doom Builder in order to polish up his map and add a few modern amenities just for convenience sake.

I haven’t touched an editor in over 15 years so it was quite a surprise to find out how easy mapping has become. I may have gotten a little carried away with these new UDMF features and, as such, the map is designed for GZDoom. From the text file:

Doom 2 - GZDoom, hardware renderer

1 map: Not much of a challenge and roughly 10 minutes of play time. All difficulty settings implemented.

Jumping & crouching disabled, freelook is fine

Lots of Doomcute!

Making maps of your house was all the rage back-in-the-day, but I feel like this is a pretty adorable and detailed tribute to my friend and a great way to share something of him with a community we loved. Miss you, Tom.

The TL:DR is this is a really touching tribute that I’d recommend people experience. I linked the Vinny Vinesauce video because some people might not want to go through the effort of setting it up in GZDoom and might miss one or two Easter eggs playing on their own. He does a decent job exploring it. It’s so touching in fact that the creator of Doom John Romero played it.

I’d recommend not reading the Doom Wiki or anything else about it because it really takes away from what makes it special.
