Yea! Tetris, I can always get down with some Tetris.
Wasn't sure how I was getting gold, so it felt kinda bad when I got a shop, but wasn't able to buy anything. But other than that the power-ups seemed well done, and I love the snake power-up. Useful for filling holes you might have accidentally made!
My only real wish mechanics wise is the ability to spin blocks at the edge of the screen. Sort of awkward with the L/J pieces when they won't rotate at the edge.
