CITADEL - The Waterways

I just left a bunch of detailed feedback in your Twitter DMs. :)

Wow...the light reflecting off the pool of water...my jaw actually fell open at that awesome effect!
Now, I'm having some trouble proceeding after activating the 2nd blue stone. Is this part meant to be a brain exercise, or am I missing something obvious?

Loving the interconnected level design and the atmosphere - thanks so much for the sneak peek!
2022 can't come soon enough ... :)

Let me know if you want some more specific feedback. Glad to exchange thoughts!
