That was a really good game! Last level felt appropriately cool. (It was the only one where I didn't immediately have an idea for how to approach it. Though I had to change my approach for part 1 as well, because I was getting close to running out of bytes.) It was quite scary when I realized my solution had 244 bytes; I was getting worried I'd need to actually optimize that just to get a working solve. But luckily it worked without needing to make it any larger.
