Hey thank you for taking your time to read it 
So to cover your question, the game we have in 2D will be now used as a example to build it in 3D
So we keep the 2D game online while we work on the 3D, It wont be exactly like the 2D but we will definetely take the main ideas and assets and use it in our game.
I think it is wise to see keep the proposal up and if it becomes a no we will be able take the feedback from this proposal to upgrade the one we will post in the in world category. with some additional pictures and videos highlighted
