Drizzlepath: Deja Vu is a very short (around 1h) and straight forward game with achievements that are naturally unlocked by following the story. The main achievement requires you to scare away all 24 sparrows in a single game which is done by simply walking through them. Being in their proximity also triggers them to fly away. You'll find below the location of each of the 6 sparrow groups.
Fly, on your way
Scare away all 24 sparrows in a single game.
Just as the game starts, exit the pond and pass the cabin, then find a narrow path. At the beginning of it there will be 4 sparrows.
After you go past the cabin with the man sitting outside, you'll find yourself near a pond; at the beginning of the path there will be 3 sparrows.
Right before entering the dark forest, there will be a round stone arch with 5 sparrows under it.
After you exit the dark forest, continue until you reach an abandoned barn. On its left side there will be 4 sparrows.
Soon after you pass the 3 cows, you'll encounter a huge stone arc. Right past it there will be 6 sparrows, where the view changes to the ocean downhill.
Go forwards till you reach the lighthouse, circle it around until you find its door/ In front of it there are 2 sparrows.
Finish the game and return to main menu.
After you reach the lighthouse, turn back and look for an opening with a wide path towards your right. From there on, just continue till you reach the end of the game.
