Very aesthetically pleasing game! Really enjoyed the art style. As far as gameplay go I think there are some improvements that could be made for the focusing mechanic. It was a little difficult to tell whether the focusing was done on the whole screen, or on the mouse, or near the character. Perhaps making it so you have some sort of magnifying glass or focused blur effect at the mouse pointer could make it more clear what exactly is being focused on. I think this could make fighting the enemies more interesting as well. All in all though it was interesting to find all the hidden bits and beat the levels. Well done!
