            case 's': 
            y++;
            werase(win);
            box(win, 0, 0);
            mvwprintw(win, y, x, "#");
            case 'a':
            x--;
            werase(win);
            box(win, 0, 0);
            mvwprintw(win, y, x, "#");
            case 'd':
            x++;
            werase(win);
            box(win, 0, 0);
            mvwprintw(win, y, x, "#");
            default:
            break;
        }
    }

you need to have a 'break' at then end of each case – pm100 Apr 12 '22 at 18:39 — pm100, Apr 12 '22 at 18:39
Proper indentation couldn't hurt either. – Robert Harvey Apr 12 '22 at 18:42 — Robert Harvey, Apr 12 '22 at 18:42

Your are missing a break for each case

    switch(ch)
    {
        case 'w':
           y--;
           werase(win);
           box(win, 0, 0);
           mvwprintw(win, y, x, "#");
           break;
        case 's': 
           y++;
           werase(win);
           box(win, 0, 0);
           mvwprintw(win, y, x, "#");
           break
        case 'a':
           x--;
           werase(win);
           box(win, 0, 0);
           mvwprintw(win, y, x, "#");
           break;
        case 'd':
           x++;
           werase(win);
           box(win, 0, 0);
           mvwprintw(win, y, x, "#");
           break;
        default:
           break; 
    }
