Thank you for trying our game, and your feedback! My brother was in charge of the art and level design for our jam. I am pretty sure he got the models (and their animations) from Mixamo. We downscaled their textures from 4k to 512 to improve game performance, and decrease file size.
I agree with your comment on player controlled throw force. It was a part of the original scope, but was cut due to time constraints. I am glad you enjoyed our jam entry!
