An app that lets you create sprites and sprite animations for your 2D game. Unlike most sprite animation apps that create each frame as a single complete image, Spriter uses the "modular" method that breaks the animation down into many small, re-useable images (such as body parts). This approach means you'll be spending much less time redrawing all your keyframes when you want to make a single small tweak. Spriter is currently in beta and free to download for Mac, Windows and Linux or you can buy the Pro version at a discount before the app is released.
