This is some of the most fun I've with a "falling block platformer." :) I agree with sparsevector, using the player as the "cursor" for the piece positioning helps consolidate the controls incredibly well. It's also fun that the logical extension of that idea is "toroidal" wrap-around for both platforming and placement.
There's something oddly compelling about "40L Sprint but parkour." There's a lot to rethink about time attack in this format. My current PB is 3m11s, which feels a lot like sub-3 should be in reach with a little more puzzling and practice.
