Aesthetics is very much coherent. Once you type into the chat you have to click in order to get back to your person, it must be part of design but it's a tad confusing, especially since entering chat-mode doesn't allow you to scroll through the chat log or user list. I've hoped to reach the floating island in the sky but failed, I have however explored numerous environments you've prepared and all of them work well with the aesthetics you pursue.
If you're going for dead internet feel then you nailed it. I do wish they reacted to your lines somehow though.
