I have some more feedback, after playing the 0.02 demo.
First I like the addition of the campfires and the refinement is a great gameplay addition as well. The new cards are fun and the melee enemies make the difficulty progression feel smoother.
But there are also a few things I would like to suggest.
1. I feel like the standard range attack is a little weak compared to the melee. The melee has higher damge, can block projectiles and can hit multiple targets in a single hit, while range has only that, range. Also since your working with multipliers on the cards the differences in damage only get bigger, as you progress.
Two ideas to solve that would be either just a higher base damage or a second, stronger melee enemy type, so melee becomes more dangerous for the player and range has more advantage.
2. Thanks for making taking damage more notable, but the stop in music interupts the game flow in my opinion, adding a sound may be better.
3. While I like the refinement rooms, I had a run where 6 of them spawned, so maybe a limit for certain rooms, might be good.
4. Inspired by the enemy, maybe a laser beam attack would be cool, that like lasts for a certain amout of time, but takes longer to cast or reduces movement speed while casting.
One more thing, I haven't payed attention to it, so I'm not sure if it's already there or not, but the boss and later the bosses all need their own boss theme.
Thanks for listening to feedback and improving the game. I'm still excited for the full release, take your time and keep up the good work!
