Stellar Mass

Stellar Mass - the game of careful balance at celestial scale.
To play you can use the Space key, Left Mouse button, or Touchscreen.  Tap or hold your chosen button to increase the size of the star.  Release to let it begin to collapse

Score will increase every 30 frames (half second), and the closer to disaster (below 8 pixels across or above 64 pixels across), the more points you get

When the star has been stable (Yellow, middling size) for 10 seconds, 3 planets will form.  Each planet will transition between Molten, Life-Supporting, and Frozen depending on the size of the star.  It is possible to have as many as 2 Life Supporting planets at some star sizes, but those ranges are very narrow.   Life-Supporting planets add bonus points every time the score increases.
