Great game concept and surprisingly a lot deeper than you'd expect at first glance. The "presentation" is wild which is funny to say for a game that looks this simple but you get what I mean if you played it. I'm not very fast with math myself so I feel I waste a little too long doing calculations in my head, having a preview of the resulting number by hovering on your cards would be a great feature to help a little bit with that issue. Also the shield mechanic of the boss is poorly conveyed, but everything else is solid and a very cool experience.
