Two thumbs up!
Like the game alot! Been playing it for most all day long and reached level 107 before I accidentally clicked one my links and lost them game. Killed a couple of hours of my day at last (yay!). Too bad the difficulty actually decreases as you go up, since it isn't needed as many dots to stop the outbreak. It took some more time, but I definitely found the levels easier as the screen was filling with spores or bacterias or whatever.
I gather there is no end to the game, which is kind of boring. But well, it kept me entertained, so thanks a lot!
