Sadly, I wasn't able to finish my 7DRL this year. There were multiple factors that stopped me from finishing it but the main problem was that I got lost in details too much too early. Luckily, there's no permadeath in 7DRL Challenges and I'll try again next year. For those interested, I wrote a 'what went wrong' post on my blog with further failure analysis:
