Great job! Here are my thoughts on the game
- Love the music!
- I would have expected the "down" button would be drop faster, but it ends the game? I think it would be more intuitive to make it speed up/completely drop the currently falling column
- I noticed you can match columns/rows before the piece has stopped falling, which is an interesting mechanic, but since you'll be attracting people who like to play Tetris and Columns, might make more sense to wait until it lands (or is this how Columns works?)
- The graphics are nice. Very classic feel. Nice colors.
