Thank you for the suggestion. I didnt want to increase the game acceleration as the player object is already decently fast and anymore speed would make it too difficult to stop the speed as there is this sliding effect in the game. I could change it though but I mainly used it to learn all about this game development better and I seem to have gotten a lot better now.
Though making games more responsive by increasing acceleration surely seems interesting and my next simple 3D project is gonna be based on that.
