Question

There are 3 stones on the floor and 3 cages and the room is controled my a mechanism how do I get past the part of the game?

Answer 1

There are several cages on the lower level and a see-saw. You need to drag the crates onto the lower end of the see-saw, then go to the upper level and jump onto the top. The crate will then be launched onto the top level. Repeat for the other crate, then move all three crates onto switches on the floor of the top level.
