I love the game's take to the theme. Some feedback probably is try to play more around the Physics in Unity if you have time. You can also try something like translate and transform to make the penguin move in a constant speed if needed. Good job!
Oh a different language that I understood hahaha. Yeah, physics can be really really hard to play with and might take some time. But there can be alternatives so you can explore more :) Good luck on your game dev journey :)
