It is at least four to five years old, was developed in England - if I remember rightly - and all the characters in it are similar to block Minecraft. I'm not sure anymore, but the title could contain the word "If."
The game begins with a downhill elevator that leads to a party on a sort of terrace / balcony. There you should get a certain person a drink. In the further course one should photograph among other things several black birds with a camera, iron doorbells and then smash them over and over an abyss between protruding flagpoles back and forth.
Roblox?
Was it Roblox?
Unfortunately not, I do not know the game, but the graphics style is in the right direction.
Jazzpunk is the name
It was not, unfortunately, but I came straight to the right, namely "Gravity Bone". I probably confused the name with the series "Gravity Falls". So thank you!
Try to inform me again.
