The idea is nice, but I saw now why I was getting random game overs while expending! I think you also need to change the camera zoom as you get more planets connected by heat. Sometimes the planet you're trying to click is just out of camera view. But overall very nice little game! 

I see the vision of an incrementally expanding array of defensive planets, only after reading the comments and having the mechanics explained. However, there is very little decision making to be done as the player to create a good network. It feels like just luck of the draw each time whether or not your planets will be in a place to block anything. An interesting demo, maybe im just a sucker for orbits, but is not super enjoyable to play.

The game is confusing, I cannot find out why I am getting game overs or what I should be doing?

Great idea!

Loved the aesthetic and thought the idea was very cool! Little things to work on for future would be adding more info on how to play! Once i understood what to do i loved it 

I am confused on how to prevent the space invaders (viruses?) from attaching onto me especially out of the gate. I understood my goal and really loved the theming idea of this game!

Great! Unique idea and execution. Different from what I came up with when thinking about the space scale!
