Played the current build: floor 1 (two wolves), the Abandoned Smithy event, and into the floor-3 slimes. Answers to your 3 questions, then small things I noticed.
1. Yes, I'd keep going. The opening is readable in seconds: 3 energy, Strike 7 / Defend 6 / Heavy Blow 15 and an honest intent line, so every turn is a little plan.
2. What confused me:
- The first card reward offered Warcry three times (3 identical choices). If the pool allows duplicates in one reward screen, that reads like a bug and removes the choice.
- I ended the wolf fight at 77/85 and the map then showed 85/85. If a full heal after each fight is intended, say it somewhere (How to Play or a log line), because Slay-the-Spire players will plan around keeping HP.
- Playing Focus drew 2 cards but added no line to the combat log, while every attack does. Small, but the log is where I check what happened.
- Map header says "1 floors cleared" after floor 2 (the event): events don't count as cleared, and "1 floor" singular.
3. What was fun: the wolf that buffs (+1 Str) while the other one hits makes turn 1 a real choice: kill the hitter first or race the buffer. That's the kind of decision the greybox proves well.
If you want to return the favour, my hacking deck-builder demo is on my profile (DECKRYPT, ~30 min in browser), same 3 questions welcome.
