Yeah, on Easy mode it's fun. :P
I'm sorry the "gravity change" seems random, all I really did was make 2 FOFs that are 128 units tall and made them both go up and down and start on opposite sides. So the downwards wind starts at the ceiling and the upwards wind starts 64 units above the floor and they move in opposite directions of eachother... It looks pretty, screws everything up, etc. When you beat down Vol Opt ... Er, I mean, all the first boss turret things, the wind control sectors move below the floor, so the wind sectors move down into the ground as well. Your idea for some obvious visual cue is great. I could first flood the room with a light block and then with a wind block that shoves you against the ceiling, so when you see the light change you have to go to the middle sector so you're safe or something. o.o Good ideas.
