Looking at the ceiling and floor and art is exhilarating and all, but if I want to just skip to the gameplay on future playthroughs rather than listen to Wheatley for those couple minutes, is there a way to do that?
Open the developer console (with ~, after enabling it in the options), then enter the following command:
or wherever else you would like to start. If you're not currently in a game, you might need to use the map command to start one (i don't quite fully understand the difference)
Another option is to speed up that part by using
sv_cheats 1; host_timescale X with
X being a high value so you are quickly at the playable part. Just don't forget to use
sv_cheats 0 afterwards if you still want to get achievements.
Alternatively, you can use the positioning commands (also in cheats mode) to quickly teleport you there but then Wheatley will not be on par with you which might or might not be a problem for that part. The commands you will need are
find to see what parameters they need. Out of my head I think
getpos needs nothing and
X Y Z A B C where
X Y Z are coordinates and
A B C are angles.
Aliasing them and putting them in one of the config files that gets loaded offers you a quick way to skip.
