Nothing special here, just a suggestion to add a steam achievement based on time you have activated the Speed Boost, like for the wallrun.
#Speed boost achievement
cunning gull
radiant heath
just make sure its not as out of balance and ridiculous as the climb mt damavand
blissful kite
The Climb Mt. Damavand is easy, just play the game a lot 🙃
I can see marathon being an achievement though
radiant heath
it's easy but it takes twice as long as the others
blissful kite
Maybe if you're insane at the game.
I still don't have 20% of the achievements and I have Mt. Damavand.
