How to achievement get?

figure always runs backwards

получил случайно все достижения кроме одного, предположу что задача всю игру пройти с кристалом из начала игры. вопрос как это сделать, у кого получилось поделитесь...

Very much enjoyed the game. The puzzles were challenging but not absurd. Keeping the gem from "Rays" was a clever achievement. Very Indiana Jones.

So I see some tutorials and seems like should be water pointing to the right direction but in my game it is just a fountain and nothing more, I can hear the noise but can't see the water in any direction
