Hello, thank you for the reply.
I kindly wish to argue your statement about not fitting into Theme and Limitation.
Theme: You are right, that there is not that much luck involved. Although, if you throw three cards in a row onto the same opponent (e.g. hit 3x with hearts provides a two hearts heal) you get a specific combo effect regarding the suit of the card. It is kind of luck involved, whether you get the fitting suits you need to activate that combo. Furthermore, the topic wasn't luck, it was Fortune. And a fortune teller doesn't always tell you, that you are lucky, doesn't it? In our imagination, the protagonist had bad luck in the casino so he could decide for it's own fortune path, to fight his way out of casino and depths.
Limitation: You are right, that you have 5 hearts. But the limitation wasn't applied to the player health but to the combo system. Hit an enemy with a heart card, then the heart gets logged into the enemy. Now hit him with another suit. The combo indicator is gone. So you have no further chance to realize a combo on that enemy. That is an application of only one chance.
But anyway, we are grateful for your feedback and will definitely incorporate it into our game. There will be a new version of the game since the rating time of the jam is over. We would appreciate it, if you would come back for another test then.
