Really nice game, love beating scores and having to think about not just the shapes' rotation, but also the time I place it and how its lines might affect other shapes. Only suggestion I have is to have a preview of where your lines will go before you place down the block (it's pretty clear already, this would just make it easier to see where it gets blocked), and have a "Next Level" button after clearing it. Great work, lovely relaxing vibes, and all around a fun puzzle game!
