Thank you for such a detailed review deadshotninja.
I was considering going with sprites, but scaling them would make game look a bit choppy (maybe there is nice scaling and interpolation - still learning about it) + I wanted to go with agar.io style (and wanted to see how primitive drawing works).
With music I did not what music to put there (more of a me issue here).
Optimization was bad cos I over-did particles and did not test the game on machines with different configurations (something I will pay more attention too).
I am glad you liked the game and left a detailed review for it. Have a nice weekend :D
