I loved it!
It was a very cool twist on idle games with the battling system. I loved the cosmetics, I got a couple of those. And the art was done really well. Although, I do have some criticisms.
I think you should have had more rare item variety in the beginning rather than having certain items increase faster, as I couldn't see the worth as much and it was hard to keep track for decisions.
I also think you could be more clear with the battle system, maybe it's just me, but I had kind of a hard time figuring that out. Overall tho, It was pretty good!
