I already finished my snake game and it look pretty good when I execute it into cool retro term:
I need some help to fix some bugs when I try to use other unicode codes for the food, I got a frog unicode character, when I eat in horizontal way is just fine but in vertical if I need to eat from the first part if I made it from the right part of the emjo does not anything.
Here is my code:

#include <stdlib.h>

#include <ctime>
#include <time.h>
#include <errno.h>
#define N 20
#define M 40

i think this one is the part that i need to modifi to do this but i can come up when idea
void Random (){
srand(time(0));
a = 1 + rand() % 18;
b = 1 + rand() % 38;
if (Frogs == 0 && Field[a][b]==0) {
Field[a][b] = -1;
Frogs = 1;
if(speed>10 && score!=0){
speed = speed -2;
}
}
}
I was trying to use emojis instead of simple character for the food.
