Klakwall
A bat, a ball and a wall of bricks that will not wait. Every two and a half seconds the wall takes a step down the screen, and when it reaches the bat the game is over.

The games
Games
Every game and demo here is original, written from nothing in one of the books: the program, its source, and the chapters that explain every line of it.

Tunnelkin
A digger in a mine twice the height of the screen. The map lives in the console's 128 bytes of RAM, so every tunnel he digs stays dug, and the window scrolls to follow him a scanline at a time.

Cryptmorrow
An original dungeon explorer for the Commodore 64. Sixteen rooms in four zones under the hill of Morrow, three keys and three seals, skeletons and bats, and the portal of the Moss Gate.
From Cryptmorrow

Veldrin
A side-scrolling game for the Amiga 500, written on the bare metal with the operating system switched off. It boots from its own floppy, on a real A500 or in an emulator, with no Kickstart ROM needed.
From Amiga Assembly
Two Hundred and Twenty-Seven
A demo for the Amiga 500 in the old tradition of the scene — copper bars, a scroller, bobs and music, with its whole source printed and commented.
