Nice idea, rotating the puzzle pieces in the form of a falling blocks puzzle was fun. There definitely seemed to be some occasional bugginess of a block seemingly fail where it was supposed to go or looking identical to another, and sometimes the pieces would fall through each other and teleport back to the top. But the idea as a whole is super interesting and I don't think I have seen a game quite like it, feels like very much worth polishing for a casual webgame or mobile game if it interests you. :)
