I don't know if it's a bug or just a lack of Time.deltaTime but i cannot avoid the snake in any way, i keep getting eaten every single time and i can't get any points :(
To be a little positive as well, the music is very enjoyable and the graphics are very good, the snake itself doesn't move as the original games, but that is quite fun too since it gives a double twist to the formula, i hope you expand on the idea a little bit and fine tune some things so you can have a fun little game :))))
