omg zombies!
This must be fun because I keep playing despite the ability to get any further.
For something that is based predominately on a single click, it's quite attractive. Like watching your baby flourish and grow. For a few seconds...
I almost felt punished if I did too well though, because I wouldn't be able to collect coin before the next screen came up.
It seems like features I'd like to see are already in the works. Definitely expand on the series :)
