In the spirit of release early and often I have a playable alpha version of my challenge entry. I am not quite sure where is reliable to upload to so I have been trying dropbox which I've had issues with in the past, fingers crossed these links might work, please let me know if the links work / it installs and runs. The zip file is about 30-40 megs and doesn't require any installation, and is typical unity fare.

I've been developing on linux but just tested the windows version on my ancient laptop and it seems to work.
Very much a test version, I need to put in credits for things like the music and assets (need to work out how to do scrolling credits).
Instructions
When you start choose new game. You start with a certain amount of cash, and enemies start appearing in waves. You must build towers to destroy them before they destroy your base.
Click one of the 3 tower types to select it for building, then click on a location that comes up gray to build. Each tower will cost you money to build and to repair. You get cash when you kill enemies and on completing level. The enemies will move down the path towards your base but will also attack towers. If a tower is destroyed you can click on it to repair. The enemies go so close to towers when attacking they cannot defend themselves so you often have to build towers in pairs (this was more by accident than design lol).
Cameras
There are currently 3 camera types, and you can toggle between them by clicking the magnify glass icon. Overview shows the whole map from above, area mode tries to show the area where the action is taking place, and follow cam will follow the enemy of your choosing closeup. You can select which enemy to follow by clicking close to it on the path.
The path the enemies follow is darker than the rest of the terrain. You can't build on the path, or on squares that have buildings or other props on them (these will indicate red). This means you have to be strategic about where to build towers.
There's still quite a bit I intend to add, like multiple lives, high score table, balance the difficulty as you progress, more towers / enemies.
I only had enough time to play up to Level 4, but wow this is a very good! I'm shocked how fast you put all this together. Very good job! I'll play more this weekend and post back.
Keep up the great work.
