I had the same issue and my solution was: I modified the code of the game to add cheats (make my character super durable), compiled it myself and loaded the apk onto my phone. Then I finally finished the game and my addiction ended.
I think anyone hunting for a first win should play as a huntress or mage. Ranged attacks are pretty overpowered in comparison to melee and don't require as much position play. And since both classes begin with their final weapon, you don't need to rely too much on the RNG to survive.
