Got 36000! Great game, really cool! I believe every submission in this jam had to think about how to deal with difficulty, and your way is extremely well thought out. At first i didn't even check or understand the timer, concentrated on my moves, then, after a while, the pressure starts building up, really really well done!
I would like to have a shadow where the piece will land, but since you also have the shadow for the level 'goal' piece, you probably decided against it, which i also understand. Maybe a grid instead?
