Okay...um...
About the "NUTS" graphics. From the start and pause menus, there are quality options. For 30 DCoins, you can get "NUTS" graphics, which can alter the contrast and colours and also make the game look like a mess by randomising surfaces.
There are some test maps sold in the Store. They have random items and objects and character placements, and quite a few include memes and other random things. Some test the mechanics of future/other things, and some of them have items and artifacts that do random things. For example, the nuclear pigeon has "NANI!?" written on it with some eye flares and spews out 50 fast-moving flashes at once when used, the "PIGEON GOD TRUE SUCC FORM" is very large and spawns a circle of muffins, flashes everywhere and throws tons of items everywhere when used, inducing intense lag, the "pew-pew" is a picture of Bonzi Buddy that shoots syringes, and the "bouncy boi" is a Thiccobreather head that just bounces when you throw it or otherwise give it momentum. The last one can be brought from the Store and obtained in a loot box, by the way. So you can see how unseriously the game takes itself. And if you know anything about the creatures in the "T-POWER" map that repel three crosses and slice you to death, it's that they're memes always on Twitter and Discord. And you should see "itms". It has every item in the game in a line, all the characters gathered around, and most of the objects in the game. It's possible to access the items and see just how memetic and dumb some of them are.
That being said, there are some test maps that don't contain these things, such as "432-test", which demonstrates SCP-432 in isolation. But my point is, just, it would complicate everything if the Store was incorporated into the storyline at all. There are lots and lots of random, 100% uncanon things in it, which I've just pointed out, including meta and experimental things and random memes and effects and things to mess with for MrDrNose's and the players' enjoyment. If you're going to rework the Store, you WILL need a plan for them. The best I can suggest is to leave the maps on the main menu. The main and pause menus are also very meta, so I don't know what you'll do with the "NUTS" graphics. And you'll need a good plan for the DStore if it does get incorporated.
I think you should just type in Korean if it helps, and we'll just translate it with Google or some fellows if we have any. And if you can't read this comment, translate it in turn and see if it does anything.
By the way I just pasted the contents of your documents into replies underneath that of MrDrNose's. Didn't really need to download text files when it could be done here. And yes, you probably should join Discord. It's much more productive than a comment section, since it's a real-time chat room for entire communities. (Which is ironic since I wasted entire days on it, so it was probably a good thing anyway I was kicked...I only intend to watch now, for some time. Being out of the loop sucked.)
