The game is cool but hard. I don't like that you can lose all your hearts and do everything from the beginning. Without this I think it would be very fun.
And also some cards seem to harm instead of help.

I intended for playthroughs to be different, since you get different cards. So if one time it's too difficult, another time it will be easier due to getting an even amount of all cards and thus having a "balanced build". If you get too many of one card, the game will be more difficult or not as amusing.
