NIce game :) The idea to use socks is really good for the theme.
I think theres somthings you can improve like:
The movement(if you want, Jonas Tyroller did a really nice video on Youtube about this),
Adding music and sounds to give the player more feedback,
Maybe try to add an invisible tutorial or just a controls screen.
Other than that iIliked the game and I had fun playing it :) Well done!
