Nice concept. Decent execution. The particle effect is a nice touch- making it satisfying when a block is successful. The colour contrast between the arrows and the background is helpful, making it easier to notice the arrows.
Got a high score of 94.
One suggestion that I can think of is making it more obvious which side the arrows will rotate- the symbol for clockwise and ccw are both very similar to the eye and on top of that, they are moving really fast- making it hard to interpret them correctly in time.
Otherwise, it's a good game. Nice work!
