Cave Escape Room: progress report 3

 So far, planning is going swimmingly for puzzles and levels. the 3rd level has already been grey-boxed, and ideas for the 2nd level are ready to be run by the team
The primary idea is to have the 2nd level be based on a sort of crystal cave, with the positions of different coloured crystals being related to 3 gems, like with the first puzzle, and the player must pick up and move these gems to open up the way.
Each gem could be preceeded by a labyrinth or maze of sorts, or perhaps a parkour puzzle incorporating the 3 crystal colours, with each becoming more dificult as more crystals retract, regardless of the order in which they are retracted
