Hm, got stuck after the first fight... Graphics look great, though! And the chill music fits the aesthetic. For battle itself, there were couple things I noticed. First, player's health and armor were slightly faded into dark, blurring your attention from vital information. And second, the continuous "Fight" scroll appearing was kinda distracting. I would understand the first time, but for each turn? Maybe an over kill.
I would also want to point out the scaling for browser, if player doesn't want to play full screen. Now the frame hides part of the game.
Well done!
