Dear, thanks for the feedback.
I agree with you; the original TTRPG (my game is based upon) is based on rolling one dice; however I probably oversimplified the game, letting some "decision" be taken in background (i.e. what you will find in the next room, which type of enemy, which item, etc.) and leave to the player only to roll the dice to fight.
In any case, while testing the game, I realized that adding some other "perks" would beneficial. So, in the future, I may enhance the game fucusing mainly on the playability and enjoyability
