I'm Alex Smith, video game and electronic music enthusiast!

You might have heard of me as The Cynic Project. My song Matrix ][ achieved six million downloads on mp3.com back in 1999. I'm fascinated by the hidden beauty encoded in deterministic processes and stuff like fractals, cellular automata, generative music, and emergent behavior.

Music, the central feature in Pixelsphere, underpins the pitched sound effects in the game.

Scores of mallet percussion tones, as well as physically-modeled sound effects, sit within the game soundtrack. These sounds are perfectly tuned and balanced to complement the background music in Pixelsphere.

Try listening to in-browser game idly, like a streaming music player. When idle, the complete in-game soundtrack plays in the background while you use your computer.

Welcome to Pixelsphere! Sit back and listen to the music!

Interact with physical objects like bouyant crates, rolling balls, elevators, bouncy springs, and even a monster truck! All of my favorite staples from Super Mario World and Sonic the Hedgehog are featured in Pixelsphere's 30 levels. Fight baddies and manipulate gravity to solve puzzles, all while making beatiful music with each step.

Objects in Pixelsphere feature hand-drawn pixel art, modeled by hand-aligned physics, backed by the Box2D physics engine.

The Pixelsphere soundtrack

Two hours of relaxing ambient and electronic music

The Pixelsphere soundtrack is calm and relaxing...The most exciting aspect of the soundtrack is the dynamic music generation system. Each time you collect an item, you'll hear procedurally generated sequences, pre-programmed melodies, and arpeggios. These sounds blend beautifully with the background music to create a lush atmosphere and unique experience each time you play.

The 30 levels in Pixelsphere feature bouncing balls, weightless orbs, and other physical systems which trigger tones & melodies. Some systems must be played in a precise order to decrypt hidden messages. I work in a variety of styles like ambient/new age, progressive trance, house, orchestral/movie music, and chiptunes.





P i x e l - P e r f e c t - v e r s i o n

The pixel-perfect version features some slight modifications to the game:

  • Physics simulation radius increased: in ALEVEL newSimulationEnabled = (d(physicsObject.x, physicsObject.y, heroX, heroY) < 1200) ? true : false; // 1200 instead of 900 in pixel perfect version

  • Both characters, Axl and Tremolo, have the same zoom factor: zoomFactor = 1.0

  • The new browser build runs in HTML5 canvas and keeps the original 1280x720 game framing.

Consequently, you can see more of the game at once, which isn't exactly how I intended the game to look. As well, it requires a little more CPU power.

Story

The realm of Hexatonia was thought of as merely legend and folklore by the vast majority of modern civilizations on Pixelsphere. Legends speak of a curious insect-like Hexatonian race that communicated using beautiful music on a six-tone scale, the echos of which linger throughout the land to create a serene, ever-present melody that seems to hang in the air. Legend warned that these sounds were sweet enough to lure some non-Hexatonians away, completely entranced, never to return. ...

After dedicating his life to Hexatonian anthropology and the search for Hexatonia, Axl's father Maestro finally found the location of this fabled land. With proof of Hexatonia's existence, he then began work on a device called the Hexatonian Universal Translator (HUT) that would allow him to walk among his beloved specimens safely. The HUT serves to decode the knowledge and wisdom accumulated by the Hexatonians. In theory, the full, entrancing effects of the Hexatonian landscape would be filtered through the HUT before reaching the ears, allowing the non-Hexatonian wearer a safe yet still enjoyable stroll through the land. One day, Axl noticed his father was taking an unusually long stroll and decided to search for him. When he found the HUT lying on the ground just outside the Hexatonian border, he knew something was wrong. Maestro would never cast aside his prized invention so carelessly. Armed with his father's device, Axl sets off to find and retrieve his father from the fascinating land that threatens to consume him.

The story unravels as you discover the narrative of the Hexatonians. Their language consists of musical tones, and is expressed by the tension and resolution of phrases, intervals and chords. Musical markers placed throughout their world are equivalent to our "letters", but only amount to gibberish until played in a precise order.

For the desktop version, a universal fix for low framerate is changing your system screen resolution to 1280 x 960 resolution. Full screen performance may be poor. Works well on Mac and high performance PCs. Let me know how it works on your system, and send me your system specs (OS, browser, screen resolution, CPU/RAM)
