Sphaera

Sphaera is a 1999 freeware Breakout-style arcade game for PowerPC Macs by Shawn Henry (shenry@intranet.ca), built on Apple's DrawSprocket game-acceleration library. It ships ten levels of brick-bashing and was distributed through Info-Mac and Macintosh Garden as a single-developer Mac OS 9-era release.

Pitch from the author

The Info-Mac BinHex header reads: "Sphaera is a modern freeware arcade game in the spirit of the classic 'Breakout' game. It uses Apple's DrawSprocket for fast, exciting gameplay through 10 challenging levels." Distribution was free; the original project page lived at intranet.ca/~shenry/sphaera/.

System requirements

The header lists three hard requirements: a PowerPC processor, a 640x480 256-color display minimum, and Apple DrawSprocket 1.1.2 or later. Macintosh Garden adds System 7.0-7.6 and Mac OS 9 as the supported OS range.

DrawSprocket as a design choice

DrawSprocket was Apple's mid-1990s low-level display API for arcade-style titles, designed to give developers fast double-buffered fullscreen access without writing direct video-card code. Its presence here puts Sphaera firmly in the late-1990s wave of polished hobbyist Mac arcade games that piggybacked on the Game Sprockets stack.

Scope

Ten levels is a deliberately small package - this is a tightly scoped Breakout derivative, not a sprawling Arkanoid-style epic. No sequel or version 2.0 is recorded in the Info-Mac or Macintosh Garden archives.
