hey i'm using unity and i found a car script on a forum and i modify it to get rid of the input for forward and back and i was wondering if that was okey?

this is the first ludum dare game i made and it's not good but i made it and thats all that matters https://armyant-studios.itch.io/thinkfast if you wondering where i got movement code here's the link https://answers.unity.com/questions/686025/top-down-2d-car-physics-1.html also i copy and paste the code for the questions because i added a lot of easter eggs

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;
