This is a really solid game (I would try to make a pun with the thin/thick ice but I can't think of any right now)! I don't think I've seen a game quite like this before. I really like the thickness view and the double goal of going down to eat and to come up in time. The UI did seem a little out of place, so I'd recommend checking if the Canvas is worldspace or some other option then mess around with it. I know I had to do that for mine. Overall, fantastic job!
