Hey, thank you for your feedback and sorry about the frustration. We are improving this details about the game design to make it more clearer and more UX friendly in a future full release.
But just to explaing better, our ideia is about a tatic game that you have to chose when to attack or move, maybe a wrong choice will have bad consequences (and for now you need a little of lucky too XD), because your actions could happen at the same opportunity that the foes - in the rythm's time. So in addition of these, your choices need to be made in the rythm of the music (like a rythm game as well). The action responses are made through clicking the surrounding floors/tiles at the right music time, and it will result in a walk (when the space is available) or in an attack (when its filled with a foe).
Some similar games that use this kind of mechanics are Crypt of the Necrodancer and Rhythm Fighter (very good games, I really recommend them).
Anyways, thank you again to share your feeling about our game, it's very helpful to guide us in a better way of game design decisions!
