Had fun playing this one! I feel it's better to bind the zoom to click and hold mouse buttons, since scroll wheel requires longer finger movement. I also find it's hard to target and zoom the ball when it's very small. 

Neat little game, really cool idea! I do wish the scaling was off the scroll wheel though, but mostly because mine broken. But pressing a button would be nice. 

a lot of fun, love to see another ball themed game

Enjoyable game, though not too creative. I would usually give this a two for creativity since it is the first idea that comes to mind when doing games with a theme like this, but the fact that I had this ahah moment with scaling the ball was very nice so I am putting 3. Also the style is... well... just circles and rectangles so I can't really say that much about it. Though it does the job for it's purpose and that's why I am giving it a 4 in terms of enjoyment though
