Add multiple difficults

[Diranus]

The game is too easy to me so I get bored soon. :(.
The snake grows way too slow to me so it isn't difficult at all in the beginning

You should add multiple difficult levels (or game modes) where you can pick one via the select switch:

My idea:
1: As is
2: As is, but faster walking snake that grows faster
3: Like 2, but even faster
4: In the beginning like 1 but getting progressively faster walking and faster growing

Probably, multiply the snake length instead of adding one piece.
