I didn't like the fact that I must play exactly as intended, otherwise would die. Every time I play a room I can just die no matter the tactic. The only thing that matters is my card loadout, that is filled randomly. I would really like for the cards to shuffle in a way, so that there will always be a way to clear the room, and the only thing that will be punished is my choice of what resource/action I have picked(activated, not bought).
Also, just a nitpick, but could you change the yellow resource to something else or explain its value? Because now it looks like the character is so greedy, they can't get out of the collapsing cave because they still want some gold.
Other than that, the game is really good. I was flown away with the addictiveness of this gameplay(but unfair punishments pulled me out)
