I just downloaded the latest svn updates right before heading to bed. I see you updated the visor hud. I can see the clock now, but at 1680x1050 the three bars on the left side are still cut off (I didn't try 1920x1200 but I doubt that would change anything plus it makes me lag a bit). Also the breathing sounds while your helmet is on is creative but you should include an option to turn it off because it gets kind of annoying with headphones on plus I imagine it would get annoying eventually even without using headphones. I like that when you die in space your body floats and spins around a bit. Much better then how your body suddenly has gravity in space when you die with SB3. As I said, I haven't gotten to test the actual life support yet, but I just wanted to drop you a line and say keep up the good work. =)
There is an option, its in the Settings Menu in the Environments tab in the tool part of the spawn menu. I meant to make it off by default, but I forgot, and will fix that next update.
