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.
Usually I try to avoid cheats but I use them it in situations where I either get badly addicted or where I notice that I'm losing a lot of time with repetitive grinding
I just play as an archer/warden. It's a pretty easy class, I can beat the game maybe one in five times. Once you get the nature footwear artifact you've as good as won, and if you get a blooming weapon then it's a cakewalk.
Sniper is easier in my opinion. If you find a ring of marksmanship, it becomes pretty trivial with the sniper's armor bypassing and tier upgrades to the bow.
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.
