It would be really boring for anyone to watch me level building
*takes 10 minutes making room geometry, saving probably 20 times*
*takes another 10-15 minutes to set up triggers, keyholes, etc. saving another 20 or so times*
*takes half an hour to texture, saving 30+ times*
*takes 15 minutes to light it, saving another 10 times*
*play tests level, notices mistake, quits, tweaks it, goes back in*
*notices another mistake, quits, tweaks it, goes back in*
*process repeats for an hour or two*
*does it all again for the next room*
