Really the important part of the issue isn't that it it's similar to 022, it's that the old 022 sucked, and this just reminds you of it. A lot.
(The cube was also cracked, made of concrete, released more gas when you tried to get it, and was toxic as well, but that's besides the point.)
I would make it more…exciting. I've written an SCP where the main catch is the little girl begging for release and I must admit I think that SCP sucks. You need to have something other than the creepy little girl. Make it so that the creepy little girl is doing something other than begging for release, or perhaps make it a lot more obvious that the girl knows something that we don't. I know that there's the implication right now that it's much more sinister than it appears, but…eh, you're dialogue doesn't really cut it in that regard.
That's another thing. Your dialogue. Work on it. Stuff like…
Discussion cannot continue when you are enraged.
Yeah. Er. No. I would read a lot of the interview logs attached to high-rated articles, the highly-rated Foundation Tales, and ask a bit of the more experienced writers about this. As-is the dialogue is pretty stilted.
(also Able has been re-written. Go and read him again.)
