A stunning level with really unique progression and gameplay. Themed to perfection the entire way through, and the world and story this level creates is like nothing else in this game.

There isn't a single section I believe is below average, and uses 2.2 additions to enhance the decoration and storytelling perfectly. The gameplay intertwines with the decoration in an incredible way as well, such as the first part of the level having multiple routes and pathways, truly allowing the player to feel like they are exploring an abandoned and lost city.

The gameplay being somewhat learny only helps this, making the city feel like a maze, overrun by nature. The player enters a building, and goes through sections, one for every orb in the game, with gameplay that is very satisfying. The building begins to looks more clean and less overrun, as you reach above the clouds, with what is probably my favorite part of the level. The colors are warm and pretty, and there is still working technology, implying some areas of the city are still populated/have some function. The gameplay here is smooth, and retains the calm feel the music has.

Afterwards, you ascend to space, and explore a ruined space station. The background here is gorgeous, and I personally adore space themes in levels. The gameplay here includes some memory, based around broken parts of the space station, including the gameplay well into the design. The level's endscreen features the player collecting a crystal, one said to give power.

Overall, Forgotten Metropolis features gameplay that is calming, yet still remains exciting, and some of the best decoration to come from 2.2 so far. It does the song it picked justice perfectly, and this is easily one of my favorite hard demons in the game.
