Really cool level, I love this classic 1.9 style. Decent decoration for its time although its nothing special. Nothing much to say here.
The gameplay isnt anything amazing but I couldnt find any flaws and my experience was basically perfect so I gave this a 10/10 in terms of enjoyment. As you can see, I have a ton of old attempts. I tried to beat this level about 4 years ago (I failed) so it feels nice to finish it off now. I also fluked this from 52 which is nice but not very surprising, this level gets very consistent very fast. Would definitely recommend if youve already completed a few insane demons!

In terms of gameplay, this level is absolutely incredible. I had a ton of fun learning and beating this, its incredibly consistent and satisfying to play. My favorite part is definitely Jeyzors, feels awesome to play once you know which orbs to hit. Sumsars part is also quite fun although super stressful because its at the very end. The first ball was actually much better than expected since you only need to time the first click and then you just buffer all the other ones. Its a pretty tough timing that still gets pretty consistent. Overall a super fun level.
The decoration is pretty good for its time in my opinion, it all feels well polished and I cant really name a part that looks bad. Its also pretty cohesive overall. Lastly, this is my 40th insane demon :D

It’s a shame I had to beat this with LDM, but I didn’t want to risk getting lag spikes near the end. Here is a full detail video: https://youtu.be/R-z2xn_XDm4
Visually, this level is nothing short of incredible. I really don’t know what I can say about it other than that, it’s honestly one of favorite demons of all time in terms of decoration. I’m also a huge fan of the song. In terms of gameplay, it’s overall decently fun but the balancing is not very good. The first 30% is incredibly easy once you learned it, and the drop is also pretty easy. All the difficulty comes from 30% to 66%. Those parts require very precise timings and they’re very skill-based, which makes them not consistent at all. The hardest timings in the level for me were the two jumps at 47% which I died to ALL THE TIME, and it was starting to get annoying. I also died at lot at the ship part before the drop, which is unnecessarily tight and inconsistent. Even with those issues, I had a lot of fun playing this level and I recommend it. In my opinion, it’s harder than Leyak.

A very old megacollab from the gdforums, which explains its inconsistency in terms of decoration. Not much to say about it, it’s what you would expect from a 2.0 megacollab, some okay parts that aren’t interesting by any means and some weirder parts, to say the least. Despite this, I still think it feels like a finished product and it carries this very charming 2.0 feel. Definitely a nice throwback!
In terms of gameplay, this level is mostly pretty fun, however the balancing isn’t great, with a few parts in the first half being noticeably harder than the rest. It also features some annoying bits, which thankfully get consistent, or consistent enough for them to not ruin the experience. Lastly, the predrop is quite boring, especially considering it isn’t really hard at all compared to what comes next.
I had a strange experience with this level. At first, I thought it wouldn’t take me too long, but I played it for about 3 days and 5 hours in total without getting anywhere, which was really frustrating. I don’t know if that’s because it’s hard to get consistent at this level or if it’s simply because I wasn’t focusing enough. Anyway, I stopped playing this for a bit before coming back to it today and finishing it off in...less than five minutes. A pretty weird experience I had...

This is a pretty cool extreme demon created and verified by mobile players. While the decoration is not spectacular or anything, I think this is a solid level and it is quite consistent in terms of quality.
The gameplay is also good, it took me a long time to learn and most of the difficulty comes from trying to get consistent at every single part, as some of them require tons of practice, Chaz’s part (26-32%) being the prime example. Playing from 0% can be a bit frustrating at first since you keep dying to the same chokepoints (UFO timing at 19%, red orb at 25%, green orb at 27%, wave at 27%, ship part at 43%…) but all of these get consistent after a while, which allows you to get to the drop very often. The drop is incredibly fun and consistent, but the post drop (especially 75-100%) is by FAR the hardest part of the level. Almost everything single input is a difficult timing that you can realistically die to. As a result, the ending of this level is incredibly stressful and it requires a lot of focus, which is especially true for the last ship.
Overall, this is a really fun level. I also got pretty lucky, with about 10 deaths in the 70-100% range. I definitely recommend it!
