Thanks. The other choice leads to the another ending. I made it so that both endings work together to flesh out the bigger story. I recommend playing through the other choice if you haven't already.
I actually sat down to make walk animations on the last day. But I quickly realized that my animations skills sucked... So I kept it as is. I'm not sure about how much I can help but I'd be happy to take a look.
P.S: I checked out your game.
