How many stars in total?

[Nitro]

Hi, I think I have completed all of the main story with all missions having the full stars and I currently have 132 stars although the achievement didn't unlock. What am I missing? Are there more than 132 stars to collect?

There is one more star, which is given for winning the tutorial Avalanche level without any damage to your door.

Yes that was the one that I was missing, the achievement unlocked now. Thank you for clarifying, since I had no idea you could gain stars in the tutorials.

That's good to know.
Wouldn't hurt to see that in-game. I believed the crashes at lvl ends corrupted the triggers.
