Please try using the Pyxel Editor!
As of version 0.8.6, Pyxel completed implementing the planned tool. Now you can create images, tilemaps, sounds, and musics with it.

I know that there are missing features and minor bugs, so please try using it. And write something to this thread if you notice something.

You can use the Pyxel Editor with typing ```pyxeleditor``` on your terminal.
