Unfortunatly the game's point is not obvious to the player. It feels like its simply not working. I'm not saying the concept is bad, I'm simply saying it doesn't work as you intended. In fact, these issues cover whatever message you want to communicate with the game. I am not trying to figure out what it means because I am not enjoying myself interacting with the core. Suicide bombing is not about some one who has to walk 5 miles in the desert and then stand still for 2 seconds until turrets turn him red and everything blows up so he can come back to life without a scratch. I know this is not the message intented but right now, the lack of feedback and depth to the game makes the player remain on the surface of the game which doens't lead it to analyze and understand your point of view correctly.
I'm pretty sure you can come up with a way to make this fun and meaningful to the player using the mechanics you got.

In fact, I'd love to see a second version of this.
My two cents
