Click w and d to move back and forth, while using arrow keys to look around. Click on the object to "MINE" them. You can mine the NPC too. But soon he will be interactable. This will soon turn into a game. It is still really buggy. Once you mine everything, make sure to reset the project because then you don't know where you even are.
@atomicmagicnumber for his 3D Mariokart game, which I was playing and thought of making my own 3D like engine. This is not actually 3D in fact it is literally just 2.5D! Besides that all is me. @CoolTarun!
