I think most people would agree Theory of Everything 2 is the weakest of the three RobTop demons, but it’s still an incredible level in its own right.

This level really tests everything you’ve learned up to this point (excluding mirror portals). The first ship is very intimidating with all the invisible obstacles. The UFO after it requires some precise fast UFO taps which are tricky to learn. Incredibly, it’s possible to skip the slow portal going into the UFO and pass the UFO at higher speed (much harder & desyncs the song) which allows you to save time here in the speedrun, a very cool skip - unlike the Hexagon Force skip which is almost certainly unintentional, this one might be intentional, I’d love to ask RobTop about it

You have a cool memory ball followed by another UFO. This ball probably inspired the Viprin ball mazes in the Sonic series of levels so it’s worth noting. I love how the blocks and fakes correspond to the player’s primary and secondary colors

The cube after the second UFO has a few fakes that force the player to practice and learn memory gameplay - unfortunately memory mazes became a staple of 1.9 demons (not that they weren’t common before 1.9, but they certainly got more popular after 1.9’s release)

The second ship is very unique and tests the player’s ship control. Then there’s a short cube part with some unique slope gameplay.

Finally, you get to the second drop - the wave part. These waves are way tighter than Blast Processing and the higher speed can be tricky for beginners. You have another memory ball part in the middle too, which has a cool skippable platform. The second coin might be the hardest coin in any of the RobTop demons and I always have to guess it whenever I rebeat this level - in general I’m not a fan of wave coins where you have to go into the slopes

After the wave you have a cool ship part with invisible obstacles before you finally get to the break part. This break part leads into the most infamous part of the level - the 73% ship. This ship requires possibly the tightest ship control of any RobTop level (including Deadlocked) so it’s no wonder so many people have horror stories of dying repeatedly at this part. Luckily everything after this ship is pretty easy so you have a good chance of beating the level after this choke point.

You have a short memory cube, ufo, and mini wave part before you finally get to the final cube. Notably, the final cube has you end the level in the mouth of a dragon - yes, the same dragons that would be animated in 2.0 and that are present in the Deadlocked bossfight.

Overall, I love the variety of this level, but unfortunately it doesn’t have the same staying power as Clubstep or Deadlocked imo. I’d still consider this like a Top 8 RobTop level, but that’s primarily because demons are just more fun than non demons in general.

Best official level, feels the most ambitious in terms of gameplay

Always has been very fun for me to play and revisit. I feel this deviates a bit from RobTop's usual gameplay style, throwing me for quite a loop when I first attempted this. Often times, though, this level can be very satisfying to play, in a way none of Rob's other levels are. I don't like it as much as Clubstep, but that doesn't mean I do not love it.
