Love Kuraksa, love your style. Played it a little, my top score is 45920.
If player goes too fast, the rank text (Nice, Lovely, Mortal) will not appear sometimes (probably because the previous text hasn't disappeared). And the animation of sliding board when loading starts and finishes is too long. It'd be great if it'd slide away faster when loading is finished.
Can't wait for achievements and Gallery Mode!
