This was a really charming game.
Although I did feel at times the design was at odds with itself as the enemies kept giving themselves shields and I had to take sanity damage to survive/get rid of the shield only for them to put up the shield again next turn. So cards/attacks that felt like they should have been stalling tactics were effectively doing "damage" to me when enemies used them, and when I used them they also did "damage" to me.
When I was writing this comment I thought maybe I had misinterpreted the shield mechanic and it only lasted for one turn (which would have been more synergistic), but I played again and I don't think that's the case.
All that being said, I did play this for longer than the average submission I've tried, and did quite enjoy my time with it.
