I really like the gameplay!
Like others said, I think the indicator could be more obvious. I think the sweater is neat, but it's pretty hard to see. Maybe having something in UI that shows current color?

It would also be nice if colors were tagged with hotkeys (like a rhythm game), since it can be hard to swap between colors  when you're in the latter half and it gets so fast

Overall though, nice project! I hope you'll have time to make it into a more developed game

The background is great! You could improve it further by replacing the blocks with other visuals, not just plain blocks.

I like the visuals. I think with some relaxing music and more polish it could become something really special.

very nice run-cycle on the player character, good job!

I like the art aswell. Think the color indicator on the character should be way more obvious. Read the comments to know how to change colors in the first place.

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!

pressing space to switch colors was not working for me, but i really like the art :)

EDIT: it was working i am just blind lol
