What attracted me to that game were obvious references to Final Fantasy Tactics and Final Fantasy IX.
You have the basic mechanics from FFT, such as picking the direction each character faces at the end of their turn. The visual style resembles FFIX. You also start as a band of charismatic thieves.
But, the creators added card mechanics on top of that.
So each character has their own hand of random skills that you need to manage. After picking a skill, you also need to roll some dice. You perform this action by shaking your mouse (at least that part can be disabled in game settings). So, when you only want to attack the next guard, you have to deal with two layers of randomness and turns that take forever.
