Kaizo Mario Galaxy 2 Rainbow Stars | Abandoned Observatory Galaxy - The Ultimate Challenge 

yup

It definitely is a difficult star because of all the stuff you have to do without getting hit and collecting all the purple coins

It is pretty cool you get a grand star for this level

This did take several attempts to get it just right

The spring mushroom is somewhat annoying if you don't know how to control it

This is probably the hardest level in the entire mod

@@The_Clanker I'm totally agree!

That would be brutal if that happened

This is definitely one of the hardest stars as to even unlock it you have to get every normal star, beat final bowser again and then collect every single rainbow star

It is to make the level more difficult and it is a mix of all the “comet” level effects as we have the “speed-run” effect, the fast foes effect, the daredevil effect, the cosmic clones effect and the purple coins effect
