This game is eventually going to become not-free, lol. So I no longer have much hope for it. And yeah, there is no actual exploration. It's actually more of an action-arcade RPG in that the point is to pursue the highest scores and longest combos. But if you want a challenge, you have to do this thing solo...

the one hit is how much it costs to forge shit. Consistently getting 196 coins (max coin cap) solo is a bitch.
