This is a remake of Quasar's Rainbow Carol, a very iconic 2.0 level that's definitely not a bad pick to make a remake of. In fact this is one of those remakes that pay a great tribute to the original level and that play on its ideas in a respectful way.

For the most part I'd say this keeps the essence of the original and expands on it in pure fashion. Some of the effects like the background at the very start are very Quasar-ish; I definitely enjoy the effects that feel more mathematical more than the rest because that's the defining feature of Quasar's style (other than its very memorable rawness of course). It's missing some quirks that made the original so catching for me (like the full hue effect in one of the first cube parts, that made the illusion that the platforms were rotating although nothing was moving). I like the use of particles to make some of the newer effects but it's still missing that kind of "rawness" to me.

I'm not a big fan of the monochromatic designs during some of the middle parts however (like the upstairs part if I can even call it that). I know that it adds a newer vision on the level but it just kind of goes against the spirit of the original level.

I can't rate this too highly personally because I always find myself visiting original levels rather than remakes, but this is a good one on its kind. Great job.
