The art is very nice, would have been better with a couple of animations more and surely a background even simple would have greatly improved the mood, overall goo job! a little thing about performance: better providing the download too other than only the html5 to avoid performance loss on browser, i had to turn on hardware acceleration on chrome to play it properly, and this way cannot be played for example on stream.
About gameplay, the overall platforming feels a bit stiff, the controller is not very good with this kind of level design with narrow spaces, i suggest to either tweak the player controller to be more precise or to add more space in your levels, the enemies variety is a bit confusing at start, maybe would have been better to start with a bit less enemies/dangers to have their roles more clear!
Managed to find every bush, is a nice challenge, i found that i never tried to attack the enemies because it's too risky, maybe implementing a bit of knockback on attacks would be nice, because at the moment attacking leaves you too much lacking in defense.
Overall very nice entry, congratulations :D
oh and i almost forgot, the music is amazing!
