So I'm thinking of putting the attack state(all directions) in 64x64 like you said. Maybe I should just set it that way in other state too to make it uniform. As well as putting each state to their own files to make it organize . Thanks :D
Yes, if you can put all the animations in the same dimensions that would be best. And yes, to please most kinds of devs, you could have a sprite sheet and also each frame as separated files. I will definitely check out your art when it's done. :)
