Goob, i think whatever you've done is too wildly unnoticable. Mabye it's noticable to you becasue you know what your looking for.
Like when they were playtesting levels for the origininal halflife, the level designer found the solution to some puzzle so easy but a playtester owuld be stuck there for hours, this prompted redisign.
Ofcourse redisign isnt the case here becasue the only puzzle is finding out what in the world is new in this build.
(oh, and just incase you want to know, i havent tried it yet, i have exams, my last being today. Will try this afternoon)
