Thank you, glad you enjoyed the game.
I wanted the player to be able to see the enemies on the horizon as they approached but also not be top-down. I can improve upon the camera and add the ability to go from a over the shoulder to a top down so that players can choose what they want.
I have a lot of ideas for the game, like extra turrets, more playable classes with different weapons, skills for the player to use, upgrades, etc.
