I liked Fatum Betula but are there others like this one?

This is just low poly.

Super Sprint Achievement Trying to 100% this game and this is the last achievement i need and i just cant figure it out a all. Can anyone help or hint me ?

The other keys were all fairly simple to acquire or at least find, but in the world with the many long paths and shapes that form when you get close, I can't bloody find it! I've been searching for like half an hour and am totally lost! Can anyone just tell me where the hell this ♥♥♥♥♥♥♥♥♥♥♥♥♥♥ is?...

30 is a bit low. thx in advance
