I've been looking around for pixel/sprite editor, but can't find any that works for me. I've been trying to find one that plays animations and has a suitable working environment as well. Please post if you know of a good editor. Thanks!
Aseprite has a built-in animation preview. It's also pretty easy to use. It's not free but you can get it for $10 at least, which is basically nothing, or you can set your own price above $10 if you feel like it.
