Came for the Fennecs.
Found the end of the Feno... Err... Demo.
Joking around aside, when I seen "nothing else happens", I of course figured something else happened and thus was intrigued, lol! It ended up being surprisingly entertaining with the atmosphere changes and the dialog. It's also set up pretty neat in that you can't accidentally come across the secret rooms in the museum without first getting the dialog that unlocks them. So one couldn't just check walls and find the end of the demo by mistake without experiencing the rest.
One hiccup is it's a little easy to lose where you are in the dark space if you first and try to explore thinking there's a solution before trying to exit and finding a pink thing appeared with new dialog. I did find my way back to the portal with some flailing, but I guess if you don't, you can just restart as at that point you are not far in.
Ah I see! Yeah, that was my thing where I was looking all around for something, then couldn't tell where I was looking at, lol! So I did slow spins while looking up and down until I re-found it. But keeping the eyes on the horizon would eliminate that since you wouldn't be able to lose sight of the portal for long. Although that may eliminate the idea of it being somewhat disorienting. In hindsight, I probably should've picked up on that and was careful how I looked, but was tired at the time. So maybe it was more me.
