I like the artstyle and the music had a bop to it. I couldn't really dig the sin waves idea no matter how much I tried to like it. It was just more frustrating than it was challenging. It's an intuitive idea but wasn't really something for me. The camera was also a bit weird sometimes. I think for those 2D platformers it's better to keep the camera in one position because you move a lot in this game and change directions a lot. So it does get a bit shaky when you play it. Despite everything it was still a cool game and you put a lot of love into it. Great job!
