Firstly, I'd like to take the opportunity to thank Purah and the Calendra Team for this very impressively done sequel. I've been playing for the past couple of hours and the city itself is just amazing, the opening video, custom splash screen, custom music replacements for the usual Thief 2 menus and such, all top notch. I would also like to post my system specs that I'm playing with, hoping them to be helpful to any who might've found Purah's original minimum system requirements daunting (I did, but I figured I'd take the chance anyway).
Pentium 2 400MHz
192MB virtual memory (statically set)
32MB ATI Rage Fury MAXX
Soundblaster Live! Value
Running Windows ME
Playing at 800x600 resolution
And at that, with all nonessential background tasks disabled and whatnot, I feel it is very playable, so far. It is certainly somewhat choppy in the open outdoor areas, but nothing that's a problem, though granted this impression is given regarding only the first mission so far. But if your system is between this and Purah's recommendation, I think you should be able to enjoy the mission just fine, if you have a bit of patience.
Now then, onto the main reason I started this thread, hopefully this can be used as a place to post (Spoiler blocked out of course) places you're stuck at for others who've figured the section out to answer.
My question has to do with near the beginning of the Tomb:
In the room past the floortrapped passage, I can't figure out the combination of the archway colors based on the passage in the book. The first logical solution I thought of was: Yellow, Orange, Orange, Orange, Blue. But that just sent me back to the beginning, as has every combination and variation I've tried since. What am I missing in the clue? The sun's good color as it sinks should be Orange or possibly Yellow, Orange, then twice to the last should be Orange Orange or maybe Yellow Yellow, and homage to the ocean can only mean Blue to me. So, any help?
Good luck to everyone, this certainly seems to be an enjoyable mission to say the least...
Edit: I managed to figure it out while messing with it for a while longer, so nevermind.
