What you want in these kind of games is for people to play it endless...
But the reason I wouldn't play this game endlessly is because:
The ads (in general, and crashing the game)
The wind gets overused, so it's hard to make progress
Overall it's a funny game, nice graphics.
One rather major issue I've noticed is after you've upgraded to rockets, nomming on a brain slows you down, instead of boosting you
the advertisement continues to appear while im ingame and causes the game to crash.
refreshed a few times.. but it didnt help.
It's good but just a little repetitive... good music and sprites, but I think the zombie moves too slow while falling down.
