I'm just playing a game and can't solve it! Didn't find it/any help here; perhaps, its new:
Cairn
Cairn ist ein mysteriِses Adventurespiel was Hauptsنchlich aus Denkspielaufgaben besteht. Ihr reist in eine komische Welt indem wohl Wesen von überaus fortschrittlicher und mit der Natur im Einklang lebender Art gelebt haben. Es sind viele Rنtsel zu lِsen gibt um das Geheimnis dieses Ortes zu erkunden. Lest euch die Notizen durch um ein wenig Hilfe zu bekommen. Die Rنtsel sind nicht leicht zu lِsen und erfordern oftmals lنngerer ـberlegung und Beobachtung der Umwelt.
Cairn is a mistery adventuregame, mainly puzzles. You travel in a mysterious world where lived beeings together with nature. There are puzzles to solve to decover the secrets. Read the notes for a little help. Its not easy, watch and think. (My translation
)
The notes in game are in german too.

Blue notes:
- First: find more coloured stones.
- One of the poles is damaged, will see, how to repair it.
- There must be a way to roll down the round stone.
First screen, left paper
People who lived here must have had control over nature. This mechanism catches the wind. I must have more coloured stones.
Go left, another paper:
... these poles go with the wind. Who placed them that way and why? ...
Go right, paper near the plants:
... The handle of the mushroom is hollow. It extends far into the soil. One feels a draft of air by him.
