During the recent weeks I have been occasionally engrossed in playing Cytus, a rhythm game for the iOS and Android mobile platforms. Most people would probably take a look at the game and just pass it for another one of those catchy touch-based rhythm games that only become popular for a few moments then slowly and painfully die out into inexistence.
Cytus is especially unique due to it being completely designed for capacitative multi-touch screens. I have also played other touch-based rhythm games like osu! (more specifically its Android port, osu!droid) in the past, but osu! appears to be designed specifically for graphics tablets. Additionally, due to its user base consisting of mouse-trotting players, a good handful of songs available for osu! made by the players are optimized in favor of mouse players more than those who play with graphics tablets, or in my case, fingers.
Cytus is also relatively easy to pick up and learn. The gameplay is easy and intuitive. A black bar continually bounces up and down from the top to the bottom of the screen, with each direction of movement corresponding to a measure (though sometimes I think a complete round trip from top to bottom corresponds to a measure, I'll have to take time to study this). A black glow on the sides of the screen repeatedly pulses after every two 1/4 beats. Colored circles (that are colored by group depending on which trip the black line is going to and fro) pop up on the screen, and the player has to hit these circles alongside the music's rhythm. Then there are the sliders, which are a couple of smaller circles connected in a chain. The player has to slide their finger through the slider, hitting all of the smaller circles in the process. Then there's the freezes (or holds), where the player has to keep their finger on a large circle with a bar running underneath, and wait until the black line has finished traversing the entirety of the freeze bar. Because Cytus is specifically written for multi-touch screens, "jumps", where the player has to simultaneously press two or more circles at one time, can be easily implemented.
As of the time of writing, Cytus comes with 26 songs (2 are cleverly hidden, and one of the songs requires the player to like Cytus on Facebook or follow Rayark's Cytus Twitter account), most of them unique and highly enjoyable. A song in Cytus is about a bit longer than an average DDR song (most Cytus songs do not reach two minutes in length). Rayark (the development team of the game) announced that the current roster of songs in the game are currently incomplete, and there are at least a hundred more songs that are about to come out in the future. They created an interesting release plan---every hundred thousandth registered player of the game awards everybody with ten more songs, possibly an entire new chapter; with all the songs presumably unlocked for everybody by the time Cytus gets a million official players.
Notice my use of the word "official" in the last paragraph. Cytus is available for both the iOS and Android mobile platforms, though it is not free (as in both freedom and beer). iOS users are expected to shell out approximately two dollars to get to play the game. Android users can initially pay the game for free, but as they play on the second and third chapters, they must wait out a 30-second and 45-second "cooldown" period (respectively) before the song plays. F2P Android players also have song restarting disabled by default.
F2P players are not included in the release "census", for obvious reasons. Additionally, those who acquired the game illegitimately through black repositories for jailbroken iOS devices and leaked .apk's for Android devices are also (hopefully) not counted for the census.
I bought the game off Google Play (with the same price as the iOS version) because I've decided that taking a mandatory 30/45 second break between each song isn't fun.
I have a couple of gripes with Cytus, especially with the Android port, since that's where I play most of the time anyway. Firstly, the game rendering performance is awfully poor on my Asus Eee Pad Transformer TF101. I suspect that the primary reason for the lag is due to Nvidia implementing poorly-written Tegra drivers, where by doing so, they can effectively force game developers to optimize their games for the Tegra devices, rather than for every mobile GPU out there. The game runs smoothly on my HTC Desire HD, though there are some freezes here and there (but that's probably because of activities and apps fighting for CPU time in the background). There are also timing issues present within the Android port of the game, where a rather perfectly timed tap is registered with an annoying delay, turning some of my "Perfect" notes into measly "Good"s. So I can also hypothesize that some blame is to be put on the game developers themselves as well, probably because from my experience most games ported from iOS into Android are almost always badly implemented.
To solve the performance issue on my phone, I resorted to overclocking the CPU up to 1.2-1.4GHz, choosing the Performance CPU scaling governor, and/or closing every background activity and app that I can close. For my Transformer, however, overclocking the CPU doesn't seem to have any effect, nor does closing a couple of background applications. The only viable solutions I can think of are (1) just living with the game with bad lag and timing issues (I did get a couple of Million Masters with the tablet though), (2) Just play the game on my smoother phone (though thumb players will probably be a separate category for "competitions"), or (3) steal an iPad off an unfortunately picked friend who plays the game.
I also do hope that the game will offer its players the ability to import their own songs and use them in the game, though the iOS roots of the game will most likely prevent that from doing so, if the developers decide to make the iOS and Android versions of the game completely similar to each other in respect to features. It's the same thing that keeps "osu! for iOS" an unstable hack job for jailbroken iOS devices.
