The design team in bangboo adventures are using a new style.

In the first generation of these games, I would have been rewarded for jumping on top of that roof. Invisible coins would suddenly become visible when I land there.
But in current generation they no longer use this reward style.
Now they mark them in a more obvious way, for example those destructible wooden crates, if they are formed like a stair, then there is usually a reward at the top.
