From somebody who does not play shooters, i actually enjoyed this one!.
All of the 2D art is soo pretty, you got a very good artist, and a good composer as well, i like a lot the mixing of the music, the intro leitmotif at the boss fight theme adds some charm, too, i like how the music has some bright, like a toy piano for example, it fits the candy/toy theme.
I got to finish the game but i would have liked a little checkpoint after the parkour on the Boss level, because the Boss it´s hard to defeat.
