Today we (me, Romanio, Moo and K9. later somebody hidden under " " nickname joined us) played weekly game and have checked a new version of knights. That was very, very cool!)
For example, when we played "Destroy the book" quest with 2:2 teams it took something like 10 minutes to complete it) While one man is guarding a book, second is trying to get the wand. As soon as he done that - they both running to the pentagram, while opponents are trying to stop them)
Invisibility also works fine. I haven't checked it on teammates, but I like transparency (for knight himself and for observers at least) more than previous system)
About "`" button typing "/t " in the chat - that works. The only nuisance of current chat system (imho) is that you cannot quickly delete already written text. Because during a match you have to type fast: sometimes you make errors in your message, sometimes information which you want to tell became outdated (for example, location of the wand) before you will be able to press "Enter" and send it to the chat, so, you will have to delete your previous message to write new. In a critical situation that takes too much time).
P.S. Huh, just noticed what there is already a "Clear" button near the text box. Well, is there any way to activate it by keyboard, not mouse?
