Cute art, it's got a distinct style to it. I had some technical difficulties unfortunately, when I started the demo it looked like pic related.
Then in combat, I pressed what I assumed was the button to view your graveyard? It put an overlay on the screen and I was unable to interact with anything after that.
For the parts that I could play, I enjoyed. It gave off Slay the Spire vibes which is a good thing. I couldn't really tell how resources worked for casting cards though. The icon seemed like it would cost me life to cast, but that didn't seem to be the case.
