It feels that a lot of thought and effort was put into the card mechanics. I like the vibe of a complex card system. It really feels engaging. The music is really nice too. The effect will be multiplied if you pair the system with a story. Semi-static narrative parts and dialogs would fit the game atmosphere perfectly. So it’s interesting to learn if you planned something like this.
I haven’t yet progress a lot, actually. Maybe it’s only me, but the combat dragged me in, and I couldn’t get through. It would help me if there were a way to delve into the cards gradually. It may make sense to make the first combat short. Allow to win it in only a few turns. Just for the player to get that feeling and understand the core mechanics. And then introduce more creatures and cards. And by facing progressively strong opponents, learn the mechanics.
There was a strange bug on my side. The tutorial text was cut. Only about 85% of it fitted on the screen. The size of the text on the cards can be larger. It was a bit hard to read it on a laptop.
