I got Aseprite as a birthday present, one month ago.

It's a very simple tool to use with many unique features.
Want to challenge yourself by using the NES palette only? Aseprite has the palette built-in! Want to rotate things without having them look jagged? Aseprite has RotSprite! Want to make your very own MissingNo? Aseprite has the Scramble Tool!

While it's easy to draw something in any sprite editor, Aseprite has "Pixel-perfect" drawing, so you don't get those weird jagged lines when you try doing something like a curve, and "linked cels" which don't change with every frame, so you don't have to do any cut-and-paste into all the frames like I used to. The downside is that, if you accidentally forget to unlink something, it changes in all the linked frames. The good news is you have unlimited undos, unlike some of the other spriting tools I've used.

There's also things that other spriting tools have, like layers and palettes, and while Aseprite has some cool layer stuff, I haven't used it much, and if I were to talk about the palette editor, we'd be here all day.

Aseprite is worth the $15. I may have gotten it for free, but the amount of quality put into the sprite editor is enough to give away the price tag by itself. It's a nifty little thing I've already spent 100+ hours on, in the month I've had it for.
