Well..
I love Cloverfield and it's great that you're making a game for it. However there are a few things I'd like to note.
The graphics were sketchy, I liked the graphic of the monster but the city buildings were a little awkward looking a the crosshair was pretty weird too, the graphics on it kept lagging behind when I would try to move it.
Also it'd be better of the timer were an actual second counter or something, the flashing bar is kind of hard to look at and understand exactly how much time you have left. Maybe throw in some more levels or ways to increase your time or something like that a little variety and it'd be a pretty neat game!
Keep it up!
