The game concept is there, and this is a great baseplate for a game, but the goal is a bit unclear and once you realize there is almost no goal, it begins to feel pointless. The art is very appealing though, a big attractor personally. I feel if the new stages are a bit more or some other goal to work towards is clear in the beginning or found only a few minutes in would make the game more appealing to keep playing. Also, for mechanics, when there are very few, like the clicking on the cards, it does bug a bit. I feel if you want it to feel smooth to play, putting extra time into smoothing out how each mechanic works and adding a bit of feedback can go a long way in how the game feels!
Overall, love the concept, missing clear, rewarding, attainable goal. 4/10
