Audio Excursion

Audio Excursion is a very difficult demon by many people from TouchArcade.

Gameplay
The level starts out with GoodSmile's part: a 1.5 speed mini wave briefly becoming normal and then followed by a mini ship with a tight passage, where the hard part involving gravity portals with jump orbs in them. It then goes to a easier normal cube and then slow cube sequence, turning mini along the way. Then it enters Zapz's part: a 1.5 speed mini ball involving some line trolling and going down to unexpected areas. It passes through a lot of gravity portals then becomes a mini ship, this time it is considerably easier, and you tap on some jump orbs along the way to get to the top. It goes into Bio's part: a slow speed UFO with a troll at the start(where you need to stay at the bottom), also changing gravity several times. A dual mini wave part then follows, still in slow speed, then it goes into a brief Swing Copters inspired part. AbstractDark's part then follows: a rather easy looking cube part which only involves tapping jump orbs, some of them in tricky areas. It then goes to a wave part surrounded by just sawblades and switches between mini and normal mode. After a short cube part where you only tap the orbs inside gravity portals, we enter (presumably) Miggz's part. First is a wave and UFO, both with changing gravity, and then a simple ball and cube. Phantom's part follows: first a ball and cube with confusing block trolls, and then into a dual ship which involves flying through breakable blocks in other sets of blocks, also constantly changing gravity, then into a mini ship requiring straight flying. Next Goodsmile returns with a confusing dual part involving mixed forms, so one needs to watch both of them carefully. After that is Star77's part, involving ship and UFO travelling through narrow pathways and changing gravity, much reminiscent of TOE2. It briefly becomes dual before becoming a cube with confusing areas and soon a ship involving straight flying and one instance of choosing which way to go before entering Yaronoo's part: It starts with two minicube jumps before entering a ball part with a colorful background and many blocks scattered all over, and after that the level ends.

Trivia

 * This is the first TouchArcade collaboration.
 * After the success of Audio Excursion, many people on TouchArcade began to organize their own megacollabs. None of them turned out as successful as Audio Excursion.
