Works good for creating sprite sheet animations

Core functionality, creating a texture atlas (sprite sheet) with corresponding plist, works great and is very easy to use. Has some basic texture editing functionality that works in a pinch for quick edits but I would recommend getting to know Pixelmator if you need to do any serious editing. Also never really used Atlas to generate a "hit polygon" so not sure how well it works, I prefer using applications for their core functionality and PolygonVertexHelper is my preferred tool for generating bounding vertices. That said Atlas is a great tool for creating sprite sheet based animations, highly recommend.
