I had fun with the beginning but couldn't figure out the first door with two switches. There didn't seem to be enough time. The exterior view is a nice way to visualize the gravity mechanic.
Thanks a lot for playing!
If you mean this one, there's a trick to it: being high G in this position, then going back to 1.0g to make the jump gives plenty of time.
If you mean the other one with two high jumps, I agree it's a bit too tight lol, but it is possible with about a second to spare!
