Well, frankly I think this rating distribution is bullshit. 17.9% giving 1 star ratings? Which of you try-hards did that? And why is it not noted in the feedback below? 

Nice work. I played the game until the very end and really enjoyed it. The white noise being the call to summon the undead will haunt me for a while, especially since I used to listen to white noise for relaxation, LOL.

The game could use some progression elements, such as upgrades for the turrets themselves. It would also benefit from some visual feedback, especially when placing turrets. You could add a highlight effect like what is usually done in tower defense games. I was really happy that you added the speed up button; it enhanced the experience tenfold.

Question: did you use Time.timeScale to speed up the game, or did you use another method?

Great work.

Despite my best efforts, my candies were stolen by the nasty zombies :( 

Very well done game, although hard as nails. I tried beating it 5 times before giving up, and I've only gotten to the 4th wave. I'm sure there is some optimal strategy to make a perfect defence, but I was unable to find it. Maybe loosening the difficulty a bit would be a good idea.

Other than that, the game is very nicely put together and fun to play and look at. Nice job!

I love tower defense.  I thought I was pretty good at them too.  However, I did very poorly with your TD game.  Thanks to your comment below this one, I know why.
