Wow, absolutely loved this entry. Everything was well polished and felt so smooth to play! The puzzles had a nice difficulty curve as well as you introduced new pieces.
I do agree with the other commenter that the font was a little hard to read, especially in the main menu (making the font a bit darker might have helped with the main menu at least). I did get a little confused by the set of instructions regarding the green pieces, it took me a little while to understand that you were saying the green blocks were essentially the guiding and pivoting point of where your blocks would land when they were placed.
Overall though this is an incredible entry for this jam, I really enjoyed my time playing it.
