Cytus is a Rhythm Game developed for iOS, Android, and PS Vita by Rayark.The game can be described as a horizontal, non-splitscreen version of DJMAX Technika: A black scan line scrolls up and down and you must hit notes as the line goes over them. Occasionally, there are "hold" notes that must be held down until the entire note passes, and "drag" notes where the note must be dragged as the line sweeps over it.Cytus is free to download, but there is a "cooldown" when you begin a song; purchasing the paid version removes this. Currently, the game has seven chapters that are available immediately, each with 9-12 songs; you can purchase chapters 8-10 and the special "Symphony" chapter for 4.99 USD each. The latest update (Cytus 6.0) adds in ten new hidden songs from Cytus Alive, and another special chapter, K (a.k.a. Knight), for 4.99 USD. A new chapter is unlocked for all players at no extra cost for every 100,000 downloads, with the ultimate goal being to achieve 1 million downloads to make all chapters and 100 new songs available without in-app purchases.
Cytus contains examples of:
All There in the Manual: The game's official website reveals several pieces of information that aren't mentioned at all in game, including the game's storyline, and the name of the girl seen on the title screen, the app icon, and the chapter splash screens: Vanessa.
This changed with the latest update which adds the manual into the hidden songs from Cytus Alive.
Also in the same vein, the two girls featured in Chapter K are named Rosabel (Red) and Iris (Blue).
Concept Album: The "Chapter K" album tells a story inspired by the cover art for the song "Holy Knight", while the "Alive" album gives us the main plot of the game.
Double Unlock: A new chapter is revealed every 100,000 downloads, but it won't be available for play unless you purchase the chapter via Microtransactions. Alternatively, you can wait out the next few download milestones and it will become available without the need to purchase it.
Flawless Victory: Completing a song with all Perfects, and therefore the maximum score of 1 million, earns you the "Million Master" rank. Averted with getting 100% TP, which does not get its own flashy animation.
Game-Breaking Bug: The game has sync issues on certain devices. Fortunately, an update allows players to calibrate timing offsets.
Interface Spoiler: If, after completing all listed songs in a chapter, the "cleared songs" counter does not show that you've played every song in the chapter, it means there's hidden songs in the chapter.
Marathon Level: The hidden songs from Cytus Alive gives us Vanessa from Chapter Five, which is seven minutes long. Disaster and Buried from Chapter Two and Nine come close at six minutes.
On the flipside, there's The New World in Chapter Ten, which gives us the grand total of one note after the entirety of the credits in both easy and hard.
Microtransactions: The developers want to do away with this, completely but only if they can hit their goal of 1 million downloads. Until then, locked chapters may be purchased within the app, and every 100,000 downloads, a new chapter is unlocked for free for all players who have purchased the game itself.
The standard point system, which is based on your note timing and, to an extent, your combo. As there is no Life Meter, your score is used to determine whether you clear or fail a song; you need 700,000 points or better for a clear.
The "TP" system, which was implemented in repsonse to players complaining that the game's Perfect window is too wide. When you get a Perfect, you will get one of two different splashes; a a green-and-orange splash will add to your TP, while a blue splash, like the other note judgements, will not. It is theoretically possible to complete a song with a perfect score but no TP.
Secret Level: Some songs on the song select screen have splash screens that can be interacted with to unlock hidden songs. Many of these will require a guide to figure out. "Entrance" and "L" are notable in that their splash screens hide two hidden songs each. However, the hidden songs don't have their own difficulty ratings, so be prepared for anything from a typical-level chart to That One Level.
Differing from the usual Secret Levels in Cytus, Chapter K requires you to play through the first eight songs before you unlock the ninth and tenth song respectively. And yes, you have to play the ninth before you unlock the tenth.
No Name Given: The hidden songs also don't have their names listed; they're merely identified by the song entries that you unlock them on. Instead, they are often given Fan Nicknames; in the case of "L", the secret songs are known as "L Red" and "L Blue" due to the requirements to play them being to have the "L" logo glow red and blue, respectively.
