A neat idea and some pretty cute art. I wish holding control would pause the game, because like this the controls felt a bit unprecise. Like I always had to change direction one block before I wanted to, and then it would not collect the corner. Other than that it was pretty fun.
One minor complaint I would have, since you took the time to make a nice menu is that if you do make a menu this way, please add a quit button. It always feels bad having to close a game using 'alt+f4'.
Either way, a really solid jam entry! Well done!
