Reminds me of my Agar.io days. Very interesting indeed, but might get stuck in some section. I guess thats the part that requires the player to think the strategy eh. Overall, very promising to me.

And yeah that is the idea that you get stuck/trapped as you grow. I think maybe just adding more levels to explain the puzzle mechanics would have helped
