I can't stop playing this game!


I love this game. It was called Infection! before and I couldn't find it to buy stages 13-36. I wish more stages were created. I thought I'd have to pay again to get access for levels 13-36 when I switched iPhones but when I was buying the stages the program new I'd paid for them in the past and wasn't charged again! 😄

The most elegant resource-management game I’ve found


Real-time allocation of limited resources, but it isn’t a button mashing game. This requires you to think through the patterns and send your viruses where they can counter the enemy movement. 36 designed levels. Good stuff, highly replayable.

Really fun game


I loooooooove this game. There are no others like it. I like the setup of this game-really intriguing just needs a lot more levels! Mooooooore please!
