Neat idea! I included it in my Godot Community Jam compilation video series, if you’d like to take a look. :)

That's an interesting take on the Tetris gameplay, though without rotations it's indeed pretty hard to do anything :D But I guess there's only so much you can do in 24 hours ;)

Very cool twist on the tetris formula!

While an interesting game, I couldn't rotate the pieces, making it impossible to finish a line.
Could be an interesting idea however. Good job.
