This game is incredible, the amount of time spent on every single frame is unimaginable. The game has its problems, it crashes, its buggy, it lags, but my god is it good... give it a shot you won't be dissapointed.
Tips from my friend and I.
The fast travel system is hard to grasp at first, you have to use the elevators to go up and down floors, to ascend. Quests have different steps on different floors... this was the only annoying part of the game for us.
Also protip, let the person who is not hosting the game activate the elevator. This was a problem for us. the game would black screen if the host used the elevator first.
Enjoy this work of art. Hats off to you Neon Giant.
