The game itself is amazing, but there are just a couple small things related to it being a mobile port that keep it from being perfect. Primarily, hand interactions, like deselecting held cards, can be annoyingly janky. Due to this jank, it is also possible (and plausible, as it's happened to me) to accidentally play a card when you meant to put it down. I wish they'd just polish this a bit, since it's at the core of the game. If they did, I'd gladly give 5 stars.

The game itself is good but the controls really need to be streamlined for touchscreens. It seems like there is an invisible mouse cursor that stays on the screen in the last area you tapped and can lead to confusion. The game also expects you to "hover over" cards and icons sometimes to get more information, but because it's a touchscreen you have to tap and hold instead, which can lead to accidentally activating something you didn't mean to.

The core gameplay is a 10/10 it is exceptionally balanced and fun. However the one thing you do most in the game (interact with and select cards) is not ported well for touch. It's easy to see this was initially designed for a mouse cursor but it translates to an inconsistent feel for selecting cards, trying to read them, place them down etc. Many players may not care much or be bothered but I found it to be a frustrating oversight to really refine the interaction behavior with the interface.
