The idea behind this game is already part of its name: how much fun and technical capabilities can one fit into one single, tiny kilobyte? In times where the size of games has risen to many gigabytes, the fun you get from playing them has not necessarily risen the same way. This is probably one of the reasons why retro games have become so popular. But even with those games there is a trend to - relatively moderately - rising demands of memory and hardware add-ons. In contrast, the first homecomputer generation Ataris bring with them so many features and gadgets that can be brought to live with just a few commands. So what can one expect from a game of just a mere kilobyte - much less than an empty Word document nowadays consumes? For example, a horizontal scrolling space-shooter in which the landscape is generated on the fly based on the much neglected ATASCII graphical character set. Decorate this with the typical colorful capabilities of the Atari as well as an increasing level of difficulty (from 1000 points onwards it gets really difficult :) ) - here's 1K ATASCII Blaster!
The instructions for playing are obviously quite simple: Boot up the game, press fire and shoot away to crack the highscore - and watch out, it's not enough to clear just one row, as this is still too small for your spaceship, two rows are the minimum :)...
