So far so good, we agreed on an idea of two connected worlds in which you also control different characters. The characters have different properties like movement speed or jump force, they also have different equipment like a gun or a jet pack.

The plan is to present the player (hopefully you) with puzzles you can only solve in one of the worlds, the solution will then be transported over to both worlds so both of your characters can advance.
