We learned in the hard way that isn't a good idea to use textures with too much detail for the floor. It's noisy, distracting and suffer from artifacts when the camera moves. Lesson learned.
About the sword swing, indeed it lacked feedback for when it's ready to attack again, and an action bar would be a simple and effective sollution for that (I love Secret of Mana btw xD).
Thank you very much for your kind feedback, we will most certainly continue to work on this game. Cheers.
