Mmmh, it's difficult because I want vibrant backgrounds, but at the same time I know foreground elements should be easily recognizable...
I tried to work on brightness, contrast and saturation, and I've added slightly darker outlines on the characters and platforms.
Is it easier to read?
Also, yes... I see the platforms seem a little out of place and belong to a cave section (which I will do in the future)... is it better with grass on it? I'd like to keep consistency with flying platforms, so they look similar across the whole game... those purple crystals make things float (and purple could also be a colour identified with something you can jump on, maybe).
