So, Tetris is one of my favourite games, and I've always taken an interest in its 3D variations. They all suffer from the same problem, though--it's very hard to convey a 3D environment on a 2D screen. So, why not play in VR?
What it does
It's just Tetris, in 3D, in VR. You are free to rotate and move the piece within the well, as well as moving around in real life to get a better view.
What's next for 3dTris
Some better UX, since I barely had time to make this at all--a menu, some better visuals, etc.
