A nice take on the match-3 genre. Initially the controls felt a bit weird and took me a while to realize that i can only match circles at the row the cursor is at (i had matches above the cursor and thought the matching was broken) but after i figured out how to play it was a nice challenge.
My only two issues are that the controls feel a bit stiff - there is a slight delay between pressing the keys and the items sliding - and... the white background is a bit tiring to the eyes :-P
