Made through sheer force of will, with internal art content and many parts by Remedy (like that sweet logo up there), and items made by Saucy Goblin, Jaytwoster and Zoé. (and some totally serious programmer art parts/items by myself!)
Also thanks to all of these cool duders for helping out in some way, shape or form along the way: Marioalexsan, Remedy, DivergentDreams, Saucy Goblin, Nori, Shmaus, Zoé, Jaytwoster, Nyx, Zo¡!, Spicy~, Valerie, Nessie, Captain Baconator, Tea, Lone, TransientGuy, ScottyFox, Rainwolf, Hestia, Poonsplorer, Cowpy, Stone_slab442, Zeina, Rukio, Kiruex, Descen.
Here's a user manual I put together which contains guides on how to install, how to use the mod, how to make items/parts etc, I did the best I could. Explaining things is not at the forefront of my limited skillset. You can get a better overview of the mod's functions in there but check out the Discord threads for the fancy video clips!

This is the original thread I made for the mod, but it's in the age restricted channel category, so you won't be able to access it without age verification on the server.

Here's a copy of the Atlyss Discord thread but in the SFW category in Jaytwoster's server, you don't need age verification to see this one but you will miss out on all the rambling since I started the project! SFW board thread in Jaytwoster's Atlyss Community (+18) Discord
