Wow, that is awesome! I mean, it's awesome anyway, but what you just said made it even more awesome(I would point out all the good things about the PNG format and RGB/Alpha, but anyone who doesn't know what all this means can just google it).
By the way, do you think it will be possible to have a high-resolution/HD mode, which would have double-sized sprites(Perhaps it could include an "animsHD.j2a" file, or something?), and allow tilesets with double-sized tiles?
