Fun game to play. I liked how as you get larger you can absorb bigger objects and the view zooms out.
I have no idea how high I scored, but it was a fun time.
As an improvement suggestion: Make the movement speed proportional to the distance from the center of the screen. So if the player sticks to the center of the screen, the movement is slow and controlled (for consuming matter) and by moving further away you move faster to top speed (for avoiding getting killed).
Also, when I pressed on Credits there was no button to return to the main screen. Just a heads up to maybe add that to the game.
Good game!
