Protect the crystall

This is my first (finished) game and my submission for the Fireside Jam 2022.

In the game you have to Protect your magic cristall from the orcs by building towers. 

Controlls:

Move camera: WASD

Build: B or Button on screen

Zoom: Mouse wheel

Pause: Esc or Button on screen

All the other actions have buttons on the screen.

I have noticed that there is a Bug, if you click multiple times quickly at a Button in the Upgrademenue it stopps working and at the moment I don't know how to fix it. So please just don't click too fast. If it happens just reopen the menue.
