Problem with moving an object and Uni2D Colliders

hi there..

i tried to create a 2D RPG styled Game. Therefor, i created a flat map with Uni2D, and it´s physic colliders.

Everything works fine.. if i add a sphere with a rigidbody.. it collides with the Uni2D Walls. Now i tried to add a small movement script to the Sphere.

this is it:

 using UnityEngine;
 using System.Collections;
 
 public class Character_Controller : MonoBehaviour {
     
     //first the publics
     public GameObject Player;
     public GameObject SpriteHolder;
     
     public float MoveSpeed = 2.0f;
     
     
     // now the locals
     int MoveDirection;
     
     float translationH;
     float translationV;
     
     // now the functions
     // Use this for initialization
     void Start () {
         
     }
     
     // Update is called once per frame
     void Update () {
         float translationH = Input.GetAxis("Horizontal") * (MoveSpeed/10);
         float translationV = Input.GetAxis("Vertical") * (MoveSpeed/10);
         
         Player.transform.Translate(translationH, -0.001f, translationV);
         Player.transform.eulerAngles = new Vector3(0, 0, 0);
     }
 }

What happens is, that the sphere tries to climp over the colliders, floats around a bit (like rolling out) and behaves more like it´s moving on ice ._.

So i searched via Google.. and found out that i need to use the Character Controller instead of a rigidbody. Read-Done.. CC added..

But now, the object is not reacting to the colliders.. like there are no invisible walls ._.

I need this really urgently - cause this problem blocks nearly everything in my project (each NPC, object, enemy..etc needs to be able to react with the Uni2D colliders..)

What have i made wrong?
