You have inconsistent namespace spellings.

For the main module Game.cs, you have "TreehouseDefense" (with an "s"), but in the other modules you have "TreehouseDefence" (with a "c").

These should all be the same unless you intend to explicitly include them with using directives.

Ya I just caught that. Old bad spelling habits die hard sadly.

I did the same thing. It so happens that the UK and US spellings of "Defence" are different. The UK spelling is with a "c" whilst the US spelling is with an "s". The program won't care which spelling you use, as long as it's the same throughout all the files.

I've given Steven's post an up vote. Thanks Steven!

The actual spelling is your choice. The important thing is to spell it consistently throughout the project.
