Looking at the game and gameplay made me curious about the world. I want to know why I'm doing this, what am I, why does dashing through the fairy ring damages the boss. From the title, I can infer that nature is off-balance and I'm working to put it back in place, which is why the bosses are elementals, but everything else about why I'm doing this isn't clear, and I think having those things in mind would increase my motivation to continue trying the game.
I think the gameplay is a bit flawed in that I'm not truly engaging with the boss in this battle, just doing what I can to pretend it isn't there to find the fairy circle and damage it. Searching for the circle is also a bore. Ways to solve this problem would be the fairy circle being A) an attack the boss sends, and unlike the others you dodge, this one you must hit or B) a hostage of the boss, and there's something I must do to release it and let me damage the boss.
I very much like the music, and the cute rabbit thing you play as. It's a good project, enough that I want it enhanced to truly feel like liking it.
