Thank you for the kind words, and apologies that you didn't enjoy. The limited space is by design, but there should be more than enough room to ensure that every puzzle is solvable with a little shuffling. I wish I could see just how you'd gotten stuck; I thought that would be impossible given how I did the block handling. Goes to show that no matter how much you double check, things can still go wrong! Regardless, thank you for the feedback.
