This reminds me of how mobile games used to be: no forced ads, gameplay that takes genuine skill and focus (even if it isn't much), interesting mechanics that keep you coming back, and few microtransactions. Although very clearly taken massive inspiration from Archero, it has enough of its own style to stand alone. I come back daily to play the new challenges and have found them a little fun. There isn't much variety though, and I'd rather play any other Doom game, but at least it is decent!
