Blink Ability Problem

So i have this blink script that works just fine but the only problem is it doesnt go up ramps it stops the teleport when it hits a ramp that you can normally walk up without teleporting, and i need to find a way to be able to change the max ramp angle you can blink upwards on in the editor, can some provide help with this problem?

here is the script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Blink : MonoBehaviour {
public float BlinkDist = 2.5f;
private bool ASD;
private int Charge = 3;
public float Recharge = 3;
public int RechargeLim = 4;
void Start(){
Recharge = RechargeLim;
}
void Update () {
ASD = false;
if(Charge <= 2){
Recharge = Recharge - Time.deltaTime;
if(Recharge <= 0){
Charge++;
Recharge = RechargeLim;
}
}
if(Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.D)){
ASD = true;
}
if(Charge >= 1){
if(Input.GetKeyDown(KeyCode.E) && Input.GetKey(KeyCode.D)){
transform.Translate(Vector3.right * BlinkDist);
Charge--;
}
if(Input.GetKeyDown(KeyCode.E) && Input.GetKey(KeyCode.S)){
transform.Translate(-Vector3.forward * BlinkDist);
Charge--;
}
if(Input.GetKeyDown(KeyCode.E) && Input.GetKey(KeyCode.A)){
transform.Translate(-Vector3.right * BlinkDist);
Charge--;
}
if(Input.GetKeyDown(KeyCode.E)){
if(ASD == false){
transform.Translate(Vector3.forward * BlinkDist);
Charge--;
}
}
}
}
}
