In my thesis I would like to make a simple 2D platformer game on mobile devices. This is my first time making a game using the Unity Game Engine so I experienced some difficulties. I have used C# as my programming language to create my game. Discussed Tilemaps , Player movement and collision. Attached the camera to the player with Transform. Player ground check so he does not jump twice. Player can collect items and can die. I also added music to the game and many levels. Discussed many concepts like animations and animator. Then exporting the game to the mobile device.
