Fun program to use, weird in some ways. A single undo/redo level, and it has some kind of selection tools but I never actually found them, and the paint bucket has some  clever behavior; The paint visibly slides as it fills, which helps you see where it's leaking out of the shape you filled if it does. Way too slow, though.
The only program that managed to open its pcx files was grafx2, no other program (Including aseprite) was able to read them.
