I think this prototype has nailed "finding the fun" at this early prototype stage. The core gameplay of carefully choosing which card to play based on the current combat conditions definitely evokes the same feelings and thought process I get from games like Slay the Spire and Monster Train, while putting a larger focus on where monsters are positioned on the field to reap the most benefit from their effects. One piece of feedback about this prototype is regarding the play history - it's unclear to me what it's actually showing, and I couldn't quite get the benefit of going back through the history and understanding what has just happened. Otherwise, I have good hopes for the project, nicely done!
