New build is live (browser + itch.io download) with fixes from the latest round — thanks to everyone who played:
1. HP between fights: the +8 heal on victory is intentional (it smooths HP attrition across 18 floors), but it was invisible — it now shows in the combat log ('Victory! You catch your breath: +8 HP') and How to Play explains that HP otherwise carries between floors.
2. Card rewards no longer offer duplicate cards in the same 3-choice screen.
3. Focus (draw 2) now adds a line to the combat log like every other card.
4. Map header grammar fixed ('1 floor cleared').
5. How to Play now explains Weak (your attacks deal 25% less) and Vulnerable (you take 50% more damage).
The original 3 questions still stand for anyone trying the new build: (1) would you keep playing after this run, (2) what confused you, (3) what was fun?
