Thanks so much for playing and your comments, I enjoyed watching your video!
I did indeed photograph clay models to make all the sprites! I actually made the models myself out of clay then photographed them on a green screen in each different animation stage. It took quite a while to make but was a lot of fun.
I plan to update it with sounds after the jam is over, I just ran out of time and didn't get to adding the sounds. But wanted to wait until after the judging to be fair of what I actually got done in the time.
