Class 3 Outbreak Great potential but lacking in variety.
I gave this game a 4/5 and 7/10. This does not mean I think it's bad, far from it. At first glance, it must have taken a great deal of effort to painfully create all the obstacles for the zombies and civilians, the bushes that obscured the view and so on. Great kudos on that, I'm not sure I'd have the patience for something like that.
The concept, while very cliche and old, is interesting because you've used google maps for this. I wasn't sure how you'd pull it off, but it actually works surprisingly well and adds a nice feeling of realism because of how the city looks like. I also really like the little details you've put in like srpay paints on rooftops, cars blocking roads and so on, although I have to admit, it's sometimes difficult to know what will block the police's view and what won't, making point to point movements a matter of not knowing where your units will walk through to get to. But fortunately, the pathfinding never failed, so kudos on that as well.
Perhaps my biggest two problems were that you couldn't select units with the buttons 1, 2 and 3, which might seem like a minor thing, but it would also feel far more natural and easy. Also, clicking on a unit badge should select the squad. I found myself clicking on a badge and issuing orders, forgetting that I should've selected them first.
As for the other major complaint, there isn't enough variety in the game. I liked the rescue mission when it popped up, but the time limit on the second one was too short and it felt like you've cut the game short, whereas it had much more potential.
What I'd really like to see is the game playing out much more slowly. I don't mean having the units move more slowly, but the outbreak not being something trivial at one moment and suddenly having the whole map full of red dots, just to artificially move the difficulty up.
Also - it'd be great to have upgrades avaliable for your units. I agree that getting new weapons and buying upgrades might seem foolish and stupid in a time of crisis like this, but perhaps you could merge it into finding (illegal) weapons in homes and the like. Perhaps have some cars driving about or having drivable cars. But I'm going off on a tangent here, now.
Otherwise, the game was technically excellent. I really hope you'll build on this!
