Hey! I've got two news for you!
The worse one: I wasn't able to find exactly what caused the freeze for you, cause the snapshot of a game state that you provided looks good to me.
The better one: I added a way to abandon the current run! You can go to "Options" menu and select "Erase saved game" - and you'll be able to start new run from scratch.
Please let me know if that worked for you! Also, thank you very much for helping me to debug this, as well as suggesting ways to improve the gameplay - I'll do my best to hunt that bug down and implement the changes to keys next month.
