noodle

A drawing program

Noodle is currently used in the creation of various monochromatic illustration projects such as the Neauismetica, it shares a lot of the functionalities of the spritesheet editor nasu.

Noodle is written in the Uxntal programming language and is compiled with the uxn assembler, it features a handful of patterns, a pixel-perfect clean up brush, zoom functionalities and can export and import bit maps. We will write a detailed guide for this tool very soon.
