Create Two New Levels for Fire Boy and Water Girl

I need a game developer to design two new levels (one medium, one difficult than those already implemented in the attached archive) for the classic game, Water Girl and Fire Boy. The project base is also in the archive. Moreover, I need a networking system integrated into the game.

Besides these levels, I need a networking system to be implemented as well (I have worked in Unity and C#, so it would be preferable to maintain this structure).
