Congrats on submitting your first game! I liked the idea of switching between colors and it's cool that the current color is displayed on the character. It's a little small though. It reminded me of the game 'HUE'. The blue color on the belt doesn't match the one of the obstacle. I figure this is because of the color of the sky? But you could also change the cyan color of the belt to blue. Overall, a nice first entry!
