So apparently you aren't allowed to past the initial tutorial area. As soon as the elevator in the very beginning starts to go up, it auto kills the player. I almost "had it" but there's also a death barrier through the door above the elevator. Looks cool, but it's not worth trying if you cant even play. Another example of game dev's trolling people who dont buy the game.
The same textures here and there with some modifiers (ligth, normals, bumps), great method to less space consumption, but, some places may be almost identical.
