FOR ANYONE WHO WANTS TO CHECK HOW I MADE THE GAME

https://github.com/YashArvindPatel/Think-Big---GameJam-Entry

For 2D/3D Transition check this script out:

Go to the Assets -> Scripts -> Mapper3Dto2D.cs, if you just want the logic for 2D to 3D transition and vica versa.

For Game Logic check this script out:

Go to the Assets -> Scripts -> GameLogic.cs, JumpScript.cs, both combine to create the character movement and scene transistion/level transition.

If you attach this script to any cube. When it collides with the plane, the coordinates of collision are captured and GL Draw is used to map them as a basic 2D primitive shape. 

Also the Camera's render distance (fieldOfView) is lowered. I went with this instead of using a Shader on cubes because I have less experience with Shader scripts.

If you have any questions you can ask me no problem.
