Hi, as the artist I'd like to chime in on the animation looking too smooth and unnatural. Unfortunately even though I'd like to take upon animation myself someday, I still have very little experience and all the anims had a very short deadline (meaning I had to get them done fast) so that might be why it looked too smooth and unnatural. I'm glad to hear that you liked the art style though :)
You are welcome! Its difficult to make a game in such a short while and even harder to make it near flawless so its expected that issues would raise up, especially since a lot of the devs have little experience in their field making this more of a learning experience. I wish you luck with your animation and art!
Also i would also like to ask if you would mind checking out and reviewing my jam game while you are here, it would mean a lot if you would try out and tell me what you thought as well as rating it. if not thats fine but it would really help me out. My game is called Interstellar Balance encase you decide you wish to check it out.
