You're right, glossary brings me back, thanks.
T and I make Sense, but you got the whole keyboard to go for you, no need to put it all into one place, unless you want people to constantly access it quickly imo. But thats not really a major thing if you're having adjustable controls in the End, since people can just adjust it to their liking. It bugs me a bit however that you're using Y however, as I'm on a german Keyboard, so it swaps places with Z. Doesn't unity support multi language keyboard bindings? Again, not a major thing, for the same reason as above, I'm just going to assume when this is finished there will be a full options menu.
I can't really nail it down, but despite basically being the same System as in WoW as you said, the camera feels odd in Orthello.
Don't worry too much about the amount of work, unless you have a strict Deadline set, just enjoy working on it and learning as you go, it'll only become better over time, just as yourself. Looking forward to seeing your Progress over the next DDs.
