Really nice, addicting tycoon/idle(?) game. I do think giving Yuuka a way of dishing out more damage would make dealing with the increasing health of the fairies would make progression feel a bit more satisfying. Eventually, you hit a point where so many of them spawn and become tanky to the point that you just get overpowered (lol). But other than this, I found the game very charming and I think a game like this has lots of potential.
