Another little pixel editor,

Very nice, animated tiles are promised soon though.
Very NIce!!! But I think pixel art, it´s awesoming difficult.... it´s very impressive, but very hardest work..
It is a beautiful interface and it supports a lot of stuff similar to gimp and photoshop.
Oooh, looks like a nice replacement for Tile Studio, which was my favourite pixel editor but unfortunately doesn't appear to be in development anymore.
BTW .pyxel files are just zips, with .PNG files and one .JSON file for the data structure within.
