I love the overall look and feel of the game. The graphics are great, especially for an IO game and the UI seems to work really well with it. I think the gameplay of having 6 opponents and making it time limited to just 2 minutes is a great way to get a bite of gameplay when there isn't much time available. The one area that I think would really make things pop is making some improvements to the overall "juice" factor with little animations and general polish. Since the energy balls are such a key part of the gameplay, they should really feel alive and full of energy. They felt a little too static and the animations that pulled them in just sort of felt off (too rigid, maybe they need some more interesting easing). I think polishing up those areas will really help take the game to the next level. Great work!
