Congrats on hitting your goal.
My son has been trying to make an animated cartoon with his cousin to post to youtube. Just today he said "Wouldn't it be great if there was a way just to take the pieces you want to move and move them, instead of drawing them again?" Now there may be other software out there that does this, but it sounded very much like Spriter to me. Seems like it would be great for basic web cartoons, even just plugged into C2.
Anime studio is ready for it, with sound ^^
Spriter, one day, will be great, and I wait this day looking forward.
