I like the theme implementation! You have to strategize whether to respawn and get a turret (but waste time), or if you should stay on guard and have control over your player.
The ONLY negative I see is the AI, they weirdly "charge" at you if you get close, and it's almost unavoidable, I'd like if this attack was less sudden, idk how you would do that so nevermind.
Theme is the best part def, great job!!
