Quite an impressive remake, but there're some things you could improve:
1- The game has no Author comments. You sure you have nothing to say about the videogame you created?
2- If you get hit while your snake body closes an upper corner, you may get stuck forever (happened to me)
3- I would add some tougher late-game enemies or even boss fights because the game seems to not get harder at all after a certain amount of points (the snake body doesn't even get longer).
