Lovely take on a shoot 'em up with a charming narrative! As everyone has mentioned your assets are cohesive and look as though they belong in a storybook. I appreciate how your game mechanics correlate directly to the narrative of your character navigating the wild.
Like I had mentioned prior, my only critique would be that in the first level it's difficult to tell which items you should pick up and which you shouldn't due to the assets appearing similar. I think a quick fix would be increasing the contrast on the glow effect so that its a very noticeable "green" for good and "red" for bad.
