Playing around with static defenses

It was time to post an update for some play-testing. I've posted the current build so that one of my play-testers can explore updated features.

The upgrade system for the player ship is working to a satisfactory level and I've introduced station level turrets. The game currently has 5 towers and they are incredibly overpowered which destroys player progression. I'll be reducing it to 1 tower to start with the other 4 purchaseable through the station UI.

Have fun. Blast space zombies!!!
