Someone implemented a Tetris clone like this back in the day. Not confined to grid orientation, inertia, bouncing. You could ram pieces into place to try and complete a row. For the life of me I can’t recall the name of it, though.
Triptych? Not Tetris, but similar.
That's the one. I used enjoy that.
Also relevant: Not Tetris 2.
The thing that's grating on me is the line piece in the top-left, when "Game Over" smashes everything onto the floor, just seems to clip into the floor and half disappears with only one corner sticking out right in the middle at the end.
For a while I thought that maybe that piece was being sheared into 2 or 3 parts by the edge of the "Game Over", and I could just see one of the parts lying on the floor. But the closer I look, the less I think it's the case, and it seems more and more to be a bug in the physics engine itself. And that's really annoying me.
This happens when "game over" is such a powerful force that it can shove squishies through solids.
