Thanks for showing how to 100% (most) of the constellations.

Here's my experience:

Cancer: The cousin is hard to get, and the crabs are small. Annoying, but quick.

Pisces: Golden fish statue alluded me for a bit. Fine.

Cygnus: I'm going to go crazy. You really have to plan out a route. Hard.

Virgo: OK, this actually made me crazy. They're everywhere, they float, and if you knock one over be sure to pick her up, or else she runs through walls?, and there's a girl HIDDEN IN A BOX IN A CORNER, took 10 hours. Difficult.

Corona Borealis: Relatively tame, I just kept missing the Giraffe and the graffiti. The cousin has a crown so beat the game first.

Gemini: OH GAWD. This mission was hard in the fact that you collect twins. That's actually vaguer than you might suspect since every twin has a name. Oh, and it includes everything from people to food to animals to everything else under the sun. Pain.

Overall, the hardest challenges period. good fun.

You do not need to 100% all the constellations to get the last achievement.

When I first started playing and it said "Make Cancer" I was seriously like "WTF? Isn't this game supposed to be fun and whimsical??" and then I realised it oh yeah crabs...

Do you need to 100% all the constellations to get the last achievement?
