I have genuinely never in my life enjoyed a Tetris style game. It doesn't matter the flavor or spin (pun intended) that they've been given. That said: I had a TON of fun playing this! Legitimately a fresh concept and it fits the concept of the Jam to the letter. This has a TON of potential to actually catch on with Tetris fans if even a guy like me that doesn't enjoy the gameplay style had a good time playing it.
My only unsolicited recommendation is to maybe add an animation for the fast drop so it zips really quickly instead of the instant teleport style and maybe smoothing the rotation a little bit so it feels a BIT less snappy. Like it's swinging around to the new position a bit more than snapping to it. Overall though it was super super fun and I wish you loads of success
