I like the art style, music and UI however the shop section could be indicated better. It looks like an in-app purchase section in its current location. YOu may considering painting it with a different color or put it somewhere closer to the start button. Also, I couldn't activate the ability called "freeze". You may consider putting more explanation on that or possibly put it in the tutorial section which is even better. Other than that, it was a fun experience playing this game.
