Zombie spawn pacing is flawed.

When playing a level, there are often stretches of time where 1-2, or no zombies spawn. This is quite boring! Makes things too easy, and the level feels like a waste of my time...

As well as this, the level pacing feels off! It sometimes starts off a bit difficult, but then becomes slow paced for the rest of the level.

Hard Levels also see fit to just spam you with large numbers of zombies. I like the pacing in these, even though it can get overwhelming at the end. Easy levels, however, I dislike much more than Hard Levels, as you sit there twiddling your thumbs waiting for it to be over. At the very least, these levels should be shorter since there are less waves. (only the Easy ones of course).

There should always be a new zombie threat on screen, and it just feels wrong to wait for the next zombie.

Thanks for reading this feedback, whoever you are!
