About 1-DC

TO BE CLEAR: YOU NEED TO BE SOMEWHAT FAMILIAR WITH HOW PROGRAMMING WORKS IN ORDER TO ENJOY THIS GAME.

1-DC is an open-ended programming puzzle game (a "zach-like"), featuring a fictional low-level programming language. There are only three base commands; the rest depends on the commands' parameters (somewhat like SIC-1). This challenges the player to think in abstract and minimal terms.

How can you calculate a sine wave with only two variables? That's up to you to figure out.

Features:

  • 32 base levels;

  • 16 bonus levels, featuring negative numbers and a third variable slot;

  • A commands par in each level that you can optimize for;

  • 12 achievements, ranging from tedious to confusing;

  • A simple level editor, with more variable slots and a greater range of values

  • Voicelogs left by your boss, to inform you about his search for your missing wife.
