9Theory is a 2.0 Insane Demon created by Hinds. It is known for being styled like Theory of Everything, as well as difficult timings, insane memorization, and some tough skill segments.
Gameplay[]
The level starts with an easy cube section with a few difficult timings. Next, the player enters a ship sequence with a few moderately tight spaces as well as some tricky ship patterns. Then, there is a cube part with a few tricks as well as some timings.
This is followed by a UFO part that is moderately tight and requires some skill. There is then a relatively easy cube part with a little memorization. Then, there is a difficult ball part with some difficult timings. This is followed by a half-speed mini ship sequence comprised of tight spaces. Then, there is a relatively easy cube section, followed by a UFO section with one jump needed, and a triple spike cube jump.
Then, there is a longer UFO part with tight spaces and many portals. Later, there are two fakes. The first one involves timing while the second one involves going through the front of a block. This is followed by a cube part with some hard timings. Then, there is a relatively easy ball part. This is followed by a ship sequence comprised of moving spiked pillars and numerous gravity portals. Then, the level ends with the text "9Theory".
User coins[]
- User coin 1: Located at 43%. The player must hit the blue orb at 41-42% late to miss a yellow jump pad and collect the coin.
- User coin 2: Located at 56%. At 56%, instead of going below a spiked cube (which is the regular path), the player needs to go above it, thus taking a harder path. When taking this path, the player will be able to collect the coin.
- User coin 3: Located at 74%. It requires good UFO skills to collect.
Fails[]
- Happy crashed twice at 82%.
- Failure444 died at 82% and 83%.
- SrGuillester crashed three times at 83% and once at 85%.
Trivia[]
- The level is free to copy.
- The level contains 9,710 objects.
- The level is 1.5-styled and inspired by Theory of Everything.
- However, the level still has some 2.0 features, such as moving objects and scale/size.
- There is an Easter egg around 54%, in the mini ship section. To get into it, you must pass through a gap between two spike blocks over the ship portal, then the message "Damn..." will appear.
