I appreciate the kind words and I'm glad to hear you liked it!
I'm hoping someone plays it enough to get to the act 3 boss, there is some additional mechanics to the fight. I won't mention exactly what they are because I don't want to spoil it but I just wanted to throw that out there :).
I just replayed your game and finally reached the ending!

The strategy I used is the "no debt cards, ever" strategy, basically try to avoid the debt cards as much as possible, so the debt attack never works on me and I just keep turtling/striking till everything is killed. Also 0 relic used. Really fun! But unfortunately, the last boss' 2nd phase didn't work. She never attacked me nor do anything and her face is greyed out so I just kept striking at her face until I won. Really wished I could see how it was supposed to work ;)
Here's the deck:
