It's impressive that you managed to wrangle claude into writing 60kloc that, for the most part, works :D I noticed a few other bugs/exploits in the combat system allowing you to do infinite attacks per turn, or sometimes the game just giving you infinite turns which was especially funny when the mage punches 4 enemies to death :D
There's lots of menus to go through and this slows down the gameplay quite a bit, and I don't know what the goal is as I kept wandering in a single direction as much as possible but I never encountered anything else, except for more endless corridors and random battles of course. The combat and progression systems feel quite complex! Even though it's not completely working as intended, I enjoyed the handful of battles I had and exploring the passives of most subclasses.
During the jam I was very intrigued by your plan and I must say the end result is somewhat what I expected, but at the same time so much more. It's very impressive and I applaud you for making it happen :D great job!
