Today, I saw Pepper’s video on cement. In the description, he talked about a Hardest Coins List. So I checked it out because I was curious. Fun fact, In Silico is at 19 on that list, and I thought those coins were already super hard. So I decided to check out the Top 1, which is this level. After 1395 attempts and 7 hours, it’s finally done. Trust me, I know these coins don’t look that hard but you absolutely need to play it for yourself to realize how ridiculous they are. This is easily Insane Demon difficultly when you go for the coins, in my opinion. There are invisible triggers that you need to hit everywhere, the mini waves are ridiculous, and there are incredibly hard timings such as the transition at 44%. The last parts take a while to learn and you have to learn precise click patterns. If you want to go for those incredibly hard coins (well, they’re literally the hardest user coins), good luck. Personally, I used NoobLookingPro’s guide as I found it to be very well detailed and it helped me a lot learn how to get the coins. I’m so happy. It’s finally over!

This level looks fantastic. I love the color combos fault used since they work very well without just being the typical eye-candy colors many design creators use. Interstellar Infant offers a lot of variety in its designs keeping it fresh the whole way through. Another thing I like is how well polished it is, it’s pretty obvious much care was put into making everything look clean. Furthermore, I enjoy how well parts transition from one to the other, without using black screens or teleportals. I believe this level could’ve been made more interesting than it already it in terms of decoration, but that’s really the only thing I can say, a great level overall in terms of decoration. Note that this video uses the LDM.
In terms of gameplay, this level is pretty fun but some parts felt kind of weird to play, mostly the first ship at the drop as well as the UFO. The predrop also seemed way, way harder than the rest of the level. Unfortunately I can’t say much about the gameplay since I somehow fluked this level from 19% so I didn’t really get to experience it at all from 0. The learning process was pretty fun though.

First of all I absolutely love how this level looks, the style is executed really nicely and I particularly appreciate the pulses, especially in Sleys and Renns parts. My favorite thing about this level has to be the gameplay though. I usually dislike skill-based gameplay but I thought it was insanely satisfying to pull off here, especially the wave parts. Just about everything gets really consistent and it all feels very fair, which is awesome. I highly recommend playing this level, genuinely one of the most fun extremes Ive ever played!

This level looks fine for its time, although some parts look much better than others. I really love the song though, definitely adds a lot to the level in my opinion.
In terms of gameplay, this could have been awesome but it doesnt feel playtested at all, which kind of ruins it. Here are all the issues I have with it:
- The ship at 5% is quite annoying, some clicks dont feel intuitive at all.
- 14% is by far the biggest chokepoint in the level, the first four clicks of the spam are fine but the last one is almost completely luck-based and never gets consistent.
- The blue orb at 16% is annoying.
- The robot jumps at 20% feel quite unfair and the slopes can be slightly buggy.
- The spam at 23% is very frustrating, theres not much you can do to avoid dying there although it isnt that bad.
- 48% should speak for itself. It actually gets surprisingly consistent and it is definitely pretty satisfying to pull off though.
- The ball timing at 58% is too hard.
- 59-62% is super awkward and pretty inconsistent.
The rest of the level is actually really fun. In terms of difficulty, I think this is almost identical to SubSonic, probably slightly easier.

The best extreme demon I have ever played in terms of gameplay. The balancing is surprisingly good considering how short the level is, and overall it is just incredibly fun and satisfying to play. I don’t know what else I can say, this is just way too fun. My experience with this level was also fantastic since I somehow fluked it from 78%, which I wasn’t expecting at all, the ending being very difficult. I also really the decoration, I think it matches the song’s intensity quite well. Difficulty-wise, I think it’s harder than Ecstasy and easier than Blade of Justice. I definitely recommend this level!

Oh my god. This level’s gameplay is without a doubt the best I have ever encountered in this game. I can’t even explain how fun this is. You just need to play it, because this is unbelievably good. Not a single awkward part or timing, not a single bug, perfectly balanced, perfectly synced...The decoration is also amazing. I love gradientxd’s style, as it’s very clean and features really cool color combos and movements. Not sure this is an insane demon since it took me way less attempts and time than psychosis or the furious, but I’ll label it as such because that’s what most people think it is. Go play this level NOW.

Honestly, this level is really poorly made. All of the difficulty comes from massive chokepoints like 47% or weird bugs while the rest of the level is extremely consistent. As a result, this level feels incredibly easy in runs but getting past every single stupidly hard timing from 0 is quite difficult. The easier parts are actually really fun though. I wouldnt recommend playing this level unless you know you can beat it relatively fast.

Probably the best run I’m going to get on a copy, since there is no point in going from anywhere before Shock’s part. Definitely getting more and more consistent, also got 51% and 52% today :D
