I really like the concept here, and think it could transform into a pretty fun roguelike! It's a pretty unique spin on the genre as is.
I unfortunately had some bug issues with my playthrough though. To give context I died the first night because I didn't make enough cards, but while retrying I think I took some damage that didn't get pushed to my health, and after making it through to the 2nd I was instakilled before I got to take a turn (I suspect that damage was queued up from before), and when retrying that 2nd night I got a crash while a skeleton was moving.
That being said, not bitter! I'm a fan of deckbuilding rogues so I had a good time. I wonder if the resource gathering phase would flow better as something turn based instead of time based, because as it is it's actually more frantic than the actual battles to get resources in time.
Hope you keep at it!
