First-Person Tower Defense - Fort Defender (WIP)

This is my first Unity game. I'm the only developer and have been using most of my spare time to work on this project.

The basic concept of the game is that it's a first-person tower defence, set in medieval times. You must defend the king from incoming attackers, such as spearmen, archers and knights. Make sure you don't fall in the lava too. At the moment there's only one tower (I want to have at least 3). You can upgrade the tower with weapons, like arrows, a musket or hot oil. There are also fire rate and damage upgrades. Your player can also shoot arrows. Just click and hold to pull back, then release the mouse to let go.

I still have lots of things to do, including:

 - more towers

 - more enemies

 - music

 - more player weapons

 - better UI

 - fixing bugs
