You might be wondering why I’m uploading this incredibly old level. Well, with this level done, I have now beaten every Sley level! I think I’m the first one to do so, and it’s pretty hard to do mainly because of Toxicity (Extreme Demon) and Outer Edge (Hard-Insane Demon). Anyway, this level is actually not THAT bad, the gameplay is pretty good and the atmosphere is awesome. The main problem comes from the decoration. Also, I haven’t beaten Arb Challenge but it’s not really a full level and it will be deleted soon anyway.

Rebeat for coins, I had already beaten this 2 years ago. This is pretty fun, nothing much to say really. (Mobile) Nine Circles - Zobros [Hard demon] | Geometry Dash](https://i.ytimg.com/vi/5nVRPe2r0_g/mqdefault.jpg)

One of my favorite extreme demons in terms of gameplay. I absolutely love how this level flows, it gets incredibly consistent and it is SO satisfying to play. Additionally, this level is genuinely perfect for my skillset; fast-paced, timing gameplay is what I’m best at (and what I like the most, which is why EXPLICIT is also one of my favorite extreme demons), so I managed to beat this in a day after a lot of grinding. I highly recommend playing this level, it is unbelievably fun.

![(Mobile) Galatic Fragility Rebalanced Verified [Hard Demon] - Geometry Dash
I absolutely hate the original Galatic Fragility, so I made a rebalanced version where I fixed every single bug, and made a lot of changes to make it consistent. This is about hard demon, I’ll probably buff it because I want it to be as hard as the original level.
Changes :
0-9% : Buffed that ship A TON, tighter spaces, added some timings.
9-29% : Removed the unnecessary almost frame perfect timings and buffed the entire part to compensate. Just a bit easier and much more consistent.
29-33% : Removed some timings that you could not see.
33-42% : Nerfed 2 timings and buffed this entire part a lot, about as hard as the original, but less luck based.
42-51% : Fixed every single bug (so A LOT) and basically remade half of the part, much easier than the original and probably the most fun part.
51-64% : Buffed this part A LOT, harder timings basically everywhere, tighter flying and UFO jumps. Still, somehow more fun that the original.
64-80% : Slightly buffed, but easier to learn because of the arrows.
80-87% : Extreme buffs, basically went from a free part to a hard part that requires precision.
87-100% : Slightly nerfed.
This overall is still easier that the original because it’s so much more consistent. I had a lot of fun verifying. (Mobile) Galatic Fragility Rebalanced Verified [Hard Demon] - Geometry Dash](https://i.ytimg.com/vi/6xPJyLo0WLU/mqdefault.jpg)


![(Mobile) Windy Landscape 100% [Insane Demon] by WOOGI | Geometry Dash
I already beat this 1 year ago, but I was using FPS bypass so I felt like I needed to rebeat it for it to be 100% legit. I surprisingly beat this in literally 1 attempt, without practicing or anything before, so yeah I guess I got lucky haha. That’s an amazing and extremely fun level, play it if you haven’t already! Also, this is nowhere near insane demon difficulty, medium or hard demon would make more sense.

![(Mobile) Firewall 100% [Insane Demon] by Hinds | Geometry Dash
This is my new favorite level, at least in terms of gameplay. I think it’s by far Hinds’ best gameplay, it’s incredibly well balanced, there’s not a single annoying timing or part, and it all flows extremely well. This level does not get boring and is fun all the time. It’s also pretty hard, I think it’s my third hardest demon (Acu, Toxicity, Firewall), and my 10th insane demon. You should absolutely give it a try.
