IZC - Alpha V1.02a

Hello everyone,

Just a quick minor update. 

• Temporary disabled tool tips as it had issues with screen-sizes
• Added one new upgrade
• Renamed "Walker" to "Rotting Zombie"

I'll be working on adding a boss timer next I think. Also need to figure out how to handle large numbers and simplify them such as 1000 = 1K, 1.000,000 = 1M, etc.

Thanks for reading!
