Yes, its possible lose to RNG in current game. I will update more interesting cards and balance the card generator, so that to reduce the feeling of randomness. :D
Durability Mode is the original design, then I found a better design which is the normal mode you are playing right now. I leave a option if player want to play the old mode(durability). I am glad you like the new mode that prove I was right on the iterating.
Sound and music is in the plan. Crushing metal sound is a good direction for rock :D
