Let's see the pros. Nice driving music that keeps the heart racing, good jumping mechanics and the multi-layer parallax scrolling of the decrepit city is nice and atmospheric, as well as little touches like pigeons flying away at your approach. All in all, a fine addition to a common genre.
Now, the bad, and this, sadly, is rather a deal breaker.
It's way, way to the power of way too hard to see the zeds against the background. Several times I died and had no idea what killed me until I squinted at the screen for half a minute.
In a game of split second responses, this is terrible. Which is too bad as I'd otherwise be more than willing to give this a higher score. Not perfect, I think it needs a little added depth, like better weapons that you collect as you go, giving you a motivation that feels more weighty than 'get high score', but higher.
All the best,
Chainkiller.
