IZC - Alpha V1.02

Hey everyone,

Since I got some really decent constructive criticism, I've been working on zone advances and retreats. Now every time you advance a level you can go back once without resetting your next zone.

What does that mean?
Say you're in level 13 and it's too hard for you to farm brains? You go back one level, and it is fine. But if you go more than that, you'll have to fight your way back up to your current level. This is to prevent farming of brains.

New stuff:

• Added UI buttons that  allow you to advance to the next level, or retreat to the previous level without a penalty. If you go  back more than 1 level you'll have to fight your way back up. Think wisely.
• Added a new upgrade "Walker"

I know it's not much of an update, but as I said, I am trying my best. I know that one day, this will be the best classic incremental game of all times.

Thanks for reading,

Tricky
