Thanks all!
Escaping from teleporter room in this version is not possible. It's intended as a last chance escaping for final camping (think about the last 30 secs of SD before timelimit..)
In the next version there will be an exit from there, through the reactor room, but with a lot of damage (radiation are bad).
About lagging, what can I do? I have to do a final compile, sure, but is there anything I can do?
Thx for help and suggestions!
