After a while in there, I figured you would find another 'Simulation Test' thing which has been corrupted, which takes you to the place with lava and stuff... Hell! That's the one.
That might be an interesting idea
I normally wouldn't be too keen on the idea of backtracking, but it could provide a nice avenue to "corrupt" some already-seen parts of the base and get the evil flowing, so that could work.
Fully agreed, that would draw the map more together. As of now I have the feeling that it gets out of hand, I still get lost when playing it as it is now. The routes aren't clear and also we need to use more obvious "Key Lock Textures" next to the locked doors instead of lights, that's not obvious enough!
@Xaser - Generally, if you have ideas on how to improve the flow, the (non)linearity and the path the player is supposed to walk through in general, feel free to do your changes. I think you have a good hand in improving things like that (at least you have proven that in your latest projects very well), because as I said: ATM, it's very chaotic and you absolutely do not know where to go and what to do, I still do get lost
