The game is full of fascinating errors. It seems strange that the player is told specifically what to do in a computer game world where you are the only being whose actions are not determined by a set of pre-programmed rules, so I give the player no such instructions. Despite lack of directed purpose the artwork still has the frustrations and addictiveness of a game.

I’m using an outdated computer, which is a statement against the numbers of old computers that go to land-fill (for info on this go to www.lowtech.org), and the Luddite Tools which allow you to disrupt the game impersonate both comic–strip language and a previous generation of computer.

I’ve used a lot of devices that have very little to do with the real world. The curved space of Asteroids only affects butterflies, that fly chaotically, creating mathematically beautiful patterns. Landing on a platform can change it into another type of platform, and leaping through a cogwheel rotates the room. As well as all I have created myself the game contains the messages and disruptions of those who have played before.
