Very charming, I like this one! I just feel like the camera could be a bit more zoomed out, as the movement is quite fast and it's easy to run into a zombie. Because of that I wouldn't collect the cola, as moving even faster felt like a disadvantage. I also think some kind of timer until the next morning starts would be neat as a little goal. Oh, and please add an escape button or key when making a game in full screen mode.
