I think your visual style is really captivating, it totally caught my eye and made me play your game :-D
I get a Mario vibe when playing, except the shooting ability, and the jumping is a bit faster. It took me a while to realize that I had to press the 'C' key on my keyboard to proceed to next level, it was a good thing that you added that information on the itch page!
I loved the graphical and audio design, I think they made for a super coherent experience.
Well done, I hope you've had an awesome jam :-)
