I_EDITOR is a programming game. The goal is to write simple scripts to reproduce a drawing on screen. The commands used in the scripts move a pointer (“turtle”). The pointer has a pen, which can be up or down. When the pen is down, each move lays a print. There are additional instructions to make calculus, evaluate conditions and call previous declared sequences. The syntax and semantic are organized in language called I_CORE.

Try to reproduce the blueprints or play with the sandbox...
I will add a score and more blueprints soon ;-)
In the main menu:
Choose a blueprint or the sandbox (updown, x)
In the editor:
Choose the command in the first column (updown, x) or return to the main menu (o)
Change column (leftright)
Change the value in the second colum (x, then leftright to decreaseincrease)
Delete instruction in the second colum with (o)
Have a look on i_core thread to have more explanation about the language 'I'.
I will make a tutorial soon and post a link and additional information here.
