Yeah this ain't good. I was expecting a sandbox where I could throw any shape of piece down onto the board and watch them fall downward, but the pieces just sit there, and don't even snap into place.
The music is jarring but you had the decency to put a mute button on the top right of the screen. But the UI has no decency whatsoever! If you've looked at my other reviews then you'd know that this facet of me is really easy to impress, but small black outlines on an otherwise white screen is a bad look, even to me.
The most use I could imagine a person getting out of this is if they wanted to make a phony high-score by typing in whatever score they wanted to. But that could be made more convincing because every piece I put onto the board is a whole tetromino.
