Alright, I've decided to add a text tutorial as not all features were described in game.

Camera Controls:

Q and E to rotate left and right.

WASD to move the camera

Z and X to zoom in and out.

Placing Buildings:

Left Click to place building.

Before placing a building, press R to rotate it on the tile, then place.

Left Shift and Left Click to delete a building while hovering over it.

And that's it! Hopefully this makes it a lot more fun to play.
