This game is so addictive and filled with stuff. I like how it starts with nothing going on and then once you start unlocking stuff the game just goes nuts with content, which I find great.
Now, I've read about people's mouse cursor disappearing, and this has happened to me when the ads pop up, but I keep solving it by right-clicking, that makes the mouse cursor appear again. Maybe it doesn't work for some other people, but it does for me, so I'm really not affected. Cheers!
Also, the laptop I'm using is not really the best... or good, but I have not found any harsh lag, and that's a plus I had to throw out there.
